The only way to be right with God is to have the righteousness of Christ credited to our account.
We are corrupted by sin and unless we are delivered from THAT, the best we can do is filthy rags in the sight of God because they are tainted with sin.
Philippians 3:2-15 Look out for the dogs, look out for the evildoers, look out for those who mutilate the flesh. For we are the circumcision, who worship by the Spirit of God and glory in Christ Jesus and put no confidence in the flesh— though I myself have reason for confidence in the flesh also. If anyone else thinks he has reason for confidence in the flesh, I have more: circumcised on the eighth day, of the people of Israel, of the tribe of Benjamin, a Hebrew of Hebrews; as to the law, a Pharisee; as to zeal, a persecutor of the church; as to righteousness under the law, blameless. But whatever gain I had, I counted as loss for the sake of Christ. Indeed, I count everything as loss because of the surpassing worth of knowing Christ Jesus my Lord.
For his sake I have suffered the loss of all things and count them as rubbish, in order that I may gain Christ and be found in him, not having a righteousness of my own that comes from the law, but that which comes through faith in Christ, the righteousness from God that depends on faith— that I may know him and the power of his resurrection, and may share his sufferings, becoming like him in his death, that by any means possible I may attain the resurrection from the dead. Not that I have already obtained this or am already perfect, but I press on to make it my own, because Christ Jesus has made me his own. Brothers, I do not consider that I have made it my own. But one thing I do: forgetting what lies behind and straining forward to what lies ahead, I press on toward the goal for the prize of the upward call of God in Christ Jesus.
I’m not sure what Philippians 3 has to do with our discussion. It doesn’t say anything about sin or confessing our sins.
imardmd1 pointed us to 1 John 1, which in verse 9 states, “If we confess our sins, he is faithful and just to forgive us our sins, and to cleanse us from all unrighteousness.”
Is it your contention that God will credit the righteousness of Christ to our account without us confessing our sins?
