Friend, when our Lord gave up His life for His chosen, He died to forgive you of all your sins, not just ones you committed before you came to Christ but all that you would have committed in your life time, remember God knows all and even for all we've done and will do, He still came to give up His life for us, to cleanse us in His blood.
>“If we confess our sins, he is faithful and just to forgive us our sins, and to cleanse us from all unrighteousness.”
1 John 1:9 KJV
>“For I am persuaded, that neither death, nor life, nor angels, nor principalities, nor powers, nor things present, nor things to come, Nor height, nor depth, nor any other creature, shall be able to separate us from the love of God, which is in Christ Jesus our Lord.”
Romans 8:38-39 KJV
God loves His sheep for He is the good shepherd, praise God
