James gives believers this counsel: “Therefore, confess your sins to one another and pray for one another, that you may be healed. The prayer of a righteous person has great power as it is working.“ (James 5:16)
Below is a powerful quote from Dietrich Bonhoeffer on the wisdom of God in giving us this counsel and how confession is a means of putting sin and hypocrisy to death:
“Sin demands to have a man by himself. It withdraws him from the community. The more isolated a person is, the more destructive will be the power of sin over him, and the more deeply he becomes involved in it, the more disastrous is his isolation… This can happen even in the midst of a pious community. In confession the light of the Gospel breaks into the darkness and seclusion of the heart. The sin must be brought into the light. The unexpressed must be openly spoken and acknowledged. All that is secret and hidden is made manifest. It is a hard struggle until the sin is openly admitted. But God breaks gates of brass and bars of iron (Ps. 107:16)…”
“The root of all sin is pride… I want to be my own law, I have a right to my self, my hatred and my desires, my life and my death. The mind and flesh of man are set on fire by pride; for it is precisely in his wickedness that man wants to be as God … In the confession of concrete sins the old man dies a painful, shameful death before the eyes of a brother. Because this humiliation is so hard we continually scheme to evade confessing to a brother. Our eyes are so blinded that they no longer see the promise and the glory in such abasement.”
“Since the confession of sin is made in the presence of a Christian brother, the last stronghold of self-justification is abandoned. The sinner surrenders; he gives up all his evil. He gives his heart to God, and he finds the forgiveness of all his sin in the fellowship of Jesus Christ and his brother… Now he stands in the fellowship of sinners who live by the grace of God in the Cross of Jesus Christ.”
