“All we like sheep have gone astray; We have turned, every one, to his own way; And the Lord has laid on Him the iniquity of us all” (Isaiah 53:6)

Every saint can testify to the truth of this Scripture. This confession, while unanimous, is also individual and specific: "We have turned every one, to his own way." There’s a distinct depravity in every human being; all are sinful, but every one has individual defects. It’s a mark of saving repentance, that instead of admitting only to a general guilt for sin, the saint is not content until he’s confessed to a multitude of specific sins. "We have turned, every one to his own way", is a confession that each man sins against the light of his own conscience, so he has no right to blame others for his sin. 

 Don’t Confuse Common Repentance with Saving Repentance. The Greek word for Saving Repentance is metanoia (Strongs 3340). Saving Repentance is only experienced by regenerate saints, because it requires saving faith. The Greek word for Common Repentance is metamellomai (Strongs 3338), which is common for both sinners and saints. And yes, saints can be sorry for a sin without stopping the sin for a time. But, if the saint doesn’t want to stop the sin, he should question his salvation, because, “the children of God and the children of the devil are manifest: Whoever does not practice righteousness is not of God” (1 John 3:10).  

The way you can identify common repentance is it has regret and sorrow for sin, but doesn’t have the will to change, which is the same thing as not having the power to change. Sinners may want to change, but since they have an unregenerate heart, their will is not able to change their behavior. The way you can identify saving repentance is it confesses all sin without trying to make a deal with God, and unconditionally submits to the Lordship of Christ, and by faith, has the power to stop doing the sin repented of. 

 Saving repentance claims no rights or righteousness apart from the sacrifice of Christ. Saints know they stand guilty, without reservations, without excuses: they stand with their weapons of rebellion broken in pieces, and cry, "have mercy on me, a sinner". There’s no regret in saving repentance, because it’s always by faith in Christ. Judas committed suicide after his common repentance, but the saint with saving repentance knows "The Lord has laid on Him the iniquity of us all”, so his repentance ends in comfort and joy.
