“It is actually reported that there is sexual immorality among you, and of a kind that is not tolerated even among pagans, for a man has his father’s wife. And you are arrogant! Ought you not rather to mourn? Let him who has done this be removed from among you.
“For though absent in body, I am present in spirit; and as if present, I have already pronounced judgment on the one who did such a thing. When you are assembled in the name of the Lord Jesus and my spirit is present, with the power of our Lord Jesus, you are to deliver this man to Satan for the destruction of the flesh, so that his spirit may be saved in the day of the Lord.
“Your boasting is not good. Do you not know that a little leaven leavens the whole lump? Cleanse out the old leaven that you may be a new lump, as you really are unleavened. For Christ, our Passover lamb, has been sacrificed. Let us therefore celebrate the festival, not with the old leaven, the leaven of malice and evil, but with the unleavened bread of sincerity and truth.
“I wrote to you in my letter not to associate with sexually immoral people— not at all meaning the sexually immoral of this world, or the greedy and swindlers, or idolaters, since then you would need to go out of the world. But now I am writing to you not to associate with anyone who bears the name of brother if he is guilty of sexual immorality or greed, or is an idolater, reviler, drunkard, or swindler—not even to eat with such a one. For what have I to do with judging outsiders? Is it not those inside the church whom you are to judge? God judges those outside. ‘Purge the evil person from among you.'” 1 Corinthians 5:1-13.
Christ did not die for our sins so we could get away with sinning. He came to take away our guilt and shame so we could have peace with God, not so we could be at peace with our sin. And our sin will be with us until we are free of our mortal bodies. But we are at war with sin and temptation. Otherwise why would Jesus have said, “Woe to the world for temptations to sin! For it is necessary that temptations come, but woe to the one by whom the temptation comes!” (Matthew 18:7).
John also writes in 1 John 1:7-9, “But if we walk in the light, as he is in the light, we have fellowship with one another, and the blood of Jesus his Son cleanses us from all sin. If we say we have no sin, we deceive ourselves, and the truth is not in us. If we confess our sins, he is faithful and just to forgive us our sins and to cleanse us from all unrighteousness.” If we were free to sin without consequences after we were saved, why would this mechanism of confession and forgiveness be necessary? It is to remind us that if Christ is our Passover lamb, then we must purge sin from the house.
When I sin and confess, I am declaring my need for a Savior. If I don’t confess and receive absolution, I become sin’s ally, and a traitor to Christ. That is why I would get turned over to Satan for the destruction of my flesh. That’s why Jesus said, “And if your hand or your foot causes you to sin, cut it off and throw it away. It is better for you to enter life crippled or lame than with two hands or two feet to be thrown into the eternal fire. And if your eye causes you to sin, tear it out and throw it away. It is better for you to enter life with one eye than with two eyes to be thrown into the hell of fire.” (Matthew 18:8-9). It is better to endure punishment in the flesh than to forfeit eternal life.
