Two Mysteries: The Mystery of Iniguity and the Mystery of Godliness

The Great Controversy between Christ and Satan has two mysteries –the mystery of iniquity and the mystery of Godliness.

The phrase, “mystery of iniquity” is mentioned only one time and only in the KJV.

For the mystery of iniquity doth already work: only he who now letteth will let, until he be taken out of the way. 2 Thessalonians 2:7 KJV

Paul mentions the mystery of iniquity right after talking about a man 

Who opposeth and exalteth himself above all that is called God, or that is worshipped; so that he as God sitteth in the temple of God, shewing himself that he is God. 2 Thessalonians 2:4 KJV.

Now while the KJV uses the word “iniquity” many other versions use the word “secret.” Also many other versions use the word “lawlessness” instead of “iniquity.” I am using multiple versions to get the big picture. In 2 Thessalonians Paul is talking about someone whose secret agenda is to overthrow God’s law and set himself on God’s throne. 

Is this what also happened in heaven? Yes!

How art thou fallen from heaven, O Lucifer, son of the morning! how art thou cut down to the ground, which didst weaken the nations! For thou hast said in thine heart, I will ascend into heaven, I will exalt my throne above the stars of God:… I will ascend above the heights of the clouds; I will be like the most High. Isaiah 14:12-14 KJV

John shares more light on this mystery when he says,

And there was war in heaven: Michael and his angels fought against the dragon; and the dragon fought and his angels, Revelation 12:7 KJV

Here we see an outright war. Not with tanks and machine guns, but a war of the minds. Lucifer is secretly trying to overthrow God’s law and government in order to set up his own kingdom. I imagine he was using flattery, bribery and mind games to secretly undermine God’s law and government and turn people to himself, just as he does now.

This is where the word “iniquity” comes in. Iniquity can be described as being bent towards or inclined towards self. Ezekiel has another clue in this mystery. 

Thou wast perfect in thy ways from the day that thou wast created, till iniquity was found in thee. Ezekiel 28:15 KJV

In heaven, Lucifer’s love, which was supposed to be centered on God and others took a u-turn and headed towards himself. Somehow Lucifer mysteriously started undermining the importance of God and others and began his secret agenda of exalting self. 

When things appear unexpectedly where they are not supposed to be, we call that a mystery. Part of the famous D.B. Cooper case involves a family finding a large sum of money while hiking in the forest. It was a mystery because the money was unexpected and not supposed to be there. Was self-love supposed to be in an angel’s heart in heaven? No, it was unexpected and not supposed to be there. Was there a logical reason for Satan to be at war with Christ in heaven of all places? No. It was not logical at all. The rebellion was not supposed to be there. That makes it a mystery doesn’t it? We can’t explain it or defend it. It’s a mystery. 

Sometimes we are tempted to think, once we get to heaven we just automatically won’t sin any more, because we will be in a perfect world. Yet sin began in a perfect world! What a mystery! 

However we do know there will be no sin in heaven. 

Affliction will not rise up a second time. Nahum 1:9. NKJV

This leads us to another mystery, the mystery of Godliness. While many find it a mystery how a perfect being became so sinful, they also find it a mystery how a sinful race can become Christlike. 

Obviously this is not done on our own. This mystery can only be performed by Christ working in us. 

To them God willed to make known what are the riches of the glory of this mystery among the Gentiles: which is Christ in you, the hope of glory. Colossians 1:27 NKJV

Revelation 10 gives us another clue to the mystery. John is given a book, which I understand to be the book of Daniel. It was sweet in his mouth but bitter in his stomach. When the 2300 days in Daniel 8:14 came to an end, the expectation of Christ’s return in 1844 was sweet, but the disappointment was bitter. (I wonder if the thunders told John about the disappointment, but he was not allowed to write it down because some things must be learned through experience?) While they were disappointed in 1844 when Jesus did not return, Revelation tells us what would occur in 1844.

… but in the days of the sounding of the seventh angel, when he is about to sound, the mystery of God would be finished, as He declared to His servants the prophets. Revelation 10:7 NKJV

According to Colossians 1:27, the mystery of God is Christ in us. This leads us to the cleansing of the sanctuary, not just a building on earth or in heaven, but even more so the cleansing of the soul temple, so God can dwell right within us! See Exodus 25:8 and John 14:1-3

Again this mystery can only be accomplished by Christ working in us. It is all grace.

For the grace of God that brings salvation has appeared to all men, teaching us that, denying ungodliness and worldly lusts, we should live soberly, righteously, and godly in the present age, looking for the blessed hope and glorious appearing of our great God and Savior Jesus Christ, who gave Himself for us, that He might redeem us from every lawless deed and purify for Himself His own special people, zealous for good works. Titus 2:11-14 NKJV

In Titus 2:11-14 Paul describes a people on earth who have become Christlike. What a mystery! In heaven where you would least expect it, sin began. Now thanks to God’s grace, right here on earth, where you would least expect it, people become Christlike. John agrees with Paul. We don’t have to wait to get to heaven to be like Jesus.

Love has been perfected among us in this: that we may have boldness in the day of judgment; because as He is, so are we in this world. 1 John 4:17 NKJV

I like the way Ellen White explains it:

That which alone can effectually restrain from sin in this world of darkness, will prevent sin in heaven. The significance of the death of Christ will be seen by saints and angels. Fallen men could not have a home in the paradise of God without the Lamb slain from the foundation of the world. Shall we not then exalt the cross of Christ? The angels ascribe honor and glory to Christ, for even they are not secure except by looking to the sufferings of the Son of God. It is through the efficacy of the cross that the angels of heaven are guarded from apostasy. Without the cross they would be no more secure against evil than were the angels before the fall of Satan. Angelic perfection failed in heaven. Human perfection failed in Eden, the paradise of bliss. All who wish for security in earth or heaven must look to the Lamb of God. The plan of salvation, making manifest the justice and love of God, provides an eternal safeguard against defection in unfallen worlds, as well as among those who shall be redeemed by the blood of the Lamb. -Ellen White, Signs of the Times, December 30, 1889. 

In the Great Controversy between Christ and Satan we see a perfect angel in heaven who becomes sinful. We also see a sinful race on earth become Christ-like.

9: Reconciliation and Hope-Sabbath School Lesson Teaching Plan

Prepared by William Earnhardt, For Sabbath School Class on February 28, 2026.

Central Theme: The process of individual reconciliation is unpacked in this week’s passage. As with the cosmic sphere, it happens through the death of Christ. On the individual level, the cross, far from being a passive symbol, becomes an active reality, with God’s love transforming people as they hear the gospel and receive Christ Himself, the hope of glory.

Read in Class: Colossians 1:21-23. Ask the class to briefly summarize this passage.

Study: What is Paul alluding to with his reference to alienation and being enemies? And what is the expected end result of Christ’s death (see also Eph. 5:27)? What do you think Paul means by remaining “grounded and steadfast” in the faith? (See also Col. 2:5 and Eph. 3:17.)

Apply: What has been your experience regarding the importance of continuing to exercise faith? That is, why must you always make a conscious choice to do that? What will happen if you don’t?

Share: Your friend tells you that we need the cross for reconciliation here on earth, but the angels did not need it because they are perfect and unfallen. Therefore, once we are in heaven, we won’t need the cross either. What do you tell your friend? See Why Heaven Needed Reconciliation.

Read in Class: Colossians 1:24-25. Ask the class to identify the main idea of this passage.

Study: What does Paul say about his suffering for Christ’s sake?

Apply: Think about your own life. How might the decisions you make (big and small) fit within God’s larger plan? Can we really know whether a decision is actually “small”? How might it have larger ramifications that will become apparent only later?

Share: Your friend says that when we suffer for Christ, we are also suffering for His body, which is the church. If so, how are we suffering for each other when we are suffering for Christ? How have you suffered for the church?

Read in Class: Colossians 1:26-27, Ephesians 1:7-10, and Ephesians 3:3-6. Ask the class to identify the common thread in these passages.

Study: What is the mystery Paul is talking about in these passages, and what does this mystery have to do with the plan of salvation?

Apply: How has this mystery of the gospel already reunited you with heaven while still being right here on earth?

Share: Your friend asks you what the mystery of God is in Revelation 10, and how and when it is finished in verse 7. What do you tell your friend?

Read in Class: Colossians 1:28-29. Ask the class to identify the main idea of this passage.

Study: What is Paul’s focus? Why do you think “everyone” (NKJV and ESV) is repeated three times?

Apply: How do you understand what it means to be “perfect in Christ Jesus” (Col. 1:28)? How does an understanding of what Jesus accomplished for us at the cross help in knowing what it means to be “perfect in Christ Jesus”?

Share: Your friend asks, since Paul wants to present every man (and woman) perfect in Christ, does that mean that none of us are beyond hope of reconciliation and redemption? What do you tell your friend?

Mission: Can you think of someone who has been abused and mistreated and never really seen the love of God? How can you show them the love of goodness and God this week so they can be reconciled to Christ? See Romans 2:4.

Why Heaven Needed Reconciliation

For God in all his fullness was pleased to live in Christ, and through him God reconciled everything to himself. He made peace with everything in heaven and on earth by means of Christ’s blood on the cross. Colossians 1:19-20 NLT

Why did God need to make peace with heaven? This verse right here may help us understand just how real the war in heaven was. Even after Lucifer was cast out, those who remained may have still had their doubts. Did God really love them, or did Lucifer have some good points about God just being a tyrant?

On earth Eve was convinced God did not care for her and she needed to eat the fruit and disobey, if she really wanted to be happy.

While all this was going on, is it possible some of the remaining angels in heaven still had some questions? Have you ever been loyal to a boss not because you thought he was fair, but because you did not see any way out? So out of fear you remained loyal to him, still wishing you weren’t in that situation? If so, what did it take for you to reconcile the situation so you could have peace at work and not just conformity?

When the Son of God died on the cross He was not just atoning for Eve taking a piece of fruit she was told not to. Eve’s disobedience was a symptom of her doubts. The Cross of Christ did not just take care of the symptoms of sin. The Cross took care of sin itself! The Cross removed all doubt about God’s love. All questions in heaven and earth are answered at the cross! There can be conformity while rebellion is still in the heart. The cross goes way beyond bringing us into conformity and outward obedience. The cross replaces our thoughts of rebellion with peaceful thoughts towards God.

That which alone can effectually restrain from sin in this world of darkness, will prevent sin in heaven. The significance of the death of Christ will be seen by saints and angels. Fallen men could not have a home in the paradise of God without the Lamb slain from the foundation of the world. Shall we not then exalt the cross of Christ? The angels ascribe honor and glory to Christ, for even they are not secure except by looking to the sufferings of the Son of God. It is through the efficacy of the cross that the angels of heaven are guarded from apostasy. Without the cross they would be no more secure against evil than were the angels before the fall of Satan. Angelic perfection failed in heaven. Human perfection failed in Eden, the paradise of bliss. All who wish for security in earth or heaven must look to the Lamb of God.-Ellen White, Signs of the Times, December 30, 1889

Some have the idea that once we get to heaven, God will flip a little switch in the back of our heads that makes us stop sinning. After all, we will be in heaven and so we automatically won’t sin, right?

Wait. Where did sin begin? Heaven!

The reason why humans and angels will not sin, is the same reason why God reconciled both heaven and earth to Himself. The cross of Jesus. The cross cures the root cause of sin which is doubting God’s love. The reason there will be no sin in heaven is not due to a mechanical correction that the flip of a switch will fix. The reason there will be no sin in heaven will be because the cross will cure humans and angels alike from ever doubting God’s love, and thinking we need anything God has not given us. There will be no reason to rebel.

Rules without relationship causes rebellion. The love of Christ on the cross removes our fear of God, so we are not afraid to have an intimate relationship with Him. With our relationship cured, we will have no reason to rebel. We won’t be conformists. We will be free-thinking moral agents who are at peace with God because God is love.
