It is a form of self-condemnation, an emotion one uses against themselves to impose a punishment for the wrong they have done.
There is therefore now no condemnation to those who are in Christ Jesus, who do not walk according to the flesh, but according to the Spirit – Romans 8:1
If the word of God, which is God Himself says that we are no longer condemned as those who are in Christ, does it mean we can do all sorts of wrong and feel nothing afterwards, get away with it? No. It only means that we are now justified by faith. When we are in Christ Jesus, we are no longer supposed to be tossed to and fro by flesh. We are now subjected to the Spirit. That means when we become weak, the Holy Spirit convicts us, and if we fall, again the Holy Spirit will raise us up through justification. Therefore, we can never be unaccountable for our actions. However, the accountability comes not in the way of condemnation but in a way of a lesson.
Condemnation is one of the enemy’s ways of gaining access to a human being. The enemy doesn’t have authority or access over a human being, it is either given to him by ourselves; God (Job 1:9-12) or those closest to us. When he wants access from God he takes us to the court of God and bring against us charges to plead with God for access.
Then he showed me Joshua the high priest standing before the angel of the Lord, and Satan standing at his right side to accuse him. – Zechariah 3:1
Sometimes God gives this access, mostly when God has sent a number of rebukes and counsel to one’s actions with no heed. Then access is given to Satan until the individual calls on God in repentance, like He did with Israel over and over. This is called discipline because in the kingdom of God, discipline is key hence we have been given the Spirit of self-control. When we fall out of the instruction by the word, we do so because of lack of self-control (discipline) and every sin is unfortunately punishable to God. There is no sin that goes unpunished (Job 10:14).
And I heard a loud voice in heaven, saying: “Now have come the salvation and the power and the kingdom of our God, and the authority of His Christ. For the accuser of our brothers has been thrown down, he who accuses them day and night before our God. – Revelation 12:10
Christ did not come to condemn but to save. So justification leading to repentance is one of the forms which we are saved through. So when condemnation comes it is not from God but the accuser. God rebukes and justifies us to help us repent.
“Then neither do I condemn you,” Jesus declared. “Now go and sin no more.” – John 8:11
So when you have done wrong, the opposite of self-condemnation is coming before God, confess and ask for forgiveness. You will be justified for your actions but you will repent. You cannot accept condemnation or guilt trips not for any reason, but you can accept justification from God, repent and move on. Self-condemnation is like a double dose of medicine because it doesn’t change God’s way.
Guilt or self-condemnation is to imprison while justification leads to repentance. It is like waiting for someone’s forgiveness before you can put your error behind you and move on. It doesn’t mean that you should not apologize to them, it means you have to take the knowledge of the fact that God has forgiven you and you will receive from Him a just punishment for your mishap. Then forgive yourself, repent and move on whether the other person forgives you or not, move on.
David was a perfect example of a Repentant. He committed many mishaps but he would take punishment for each, repent and move on. He would never allow people or his mistakes hold him hostage. We have to learn from him and live a guilt-free life.
