Prayer For Grace To Accept That I Am Forgiven

Heavenly Father, I know that the Bible says that I am forgiven by  repenting of my sins and turning to Christ. I know that I am saved by grace through faith in the Lord Jesus Christ, and yet  I find that My thoughts constantly go back to my many sins and misdeed and I find that I cant accept that I have been fully and unconditionally forgiven of my sin by You.. I know that You have said that as far as the east is from the west, so far have You removed my sin from me, and yet I find that my joy in believing is often cut short as I doubt that it cannot possible be true…
Help me Lord to believe what Your Word says about my forgiveness. Give me the grace to truly accept that You have forgiven all my sins unconditional: past present and future.. and that my sins will be remembered no more.
Thank You Lord that I am forgiven. Thank You Father for sending the Lord Jesus to pay the price for my sins on the cross – I pray that in His strength I may live my life for Him every moment of the day – in Jesus name I pray,
