The forgiveness of God is grace upon grace. Colossians 2:14 shouts, "And you, being now dead in your sins and uncircumcised in your flesh, hath He quickened together with him, having forgiven you all trespasses; Blotting out the handwriting of ordinances which was against us, which was contrary to us, and took it out of the way, nailing it to His cross."
Perhaps, you are in need of a LifeChange. God can enable you to nail your sins to His cross, but you must ask God for help realizing you are insufficient without Him. We all tend to be extremely independent when God strives to help us depend more and more on Him.
Once you repent of your sins, they are nailed to the cross of Calvary and you are forgiven. Some individuals struggle daily with the pulling of sins and habits on their hearts and minds, when they need to simply leave it at the Cross with Christ. He has already paid the price for your sins, so leave them there. Give them to Christ and walk away as far in the opposite direction from your sin as possible. Christ has freed you from the bondage of sin.
