Many carry guilt around like spare baggage.   It serves no purpose.  You have all you need in Christ.   We can immediately get rid of these thoughts by confessing any transgression and believing that we are forgiven through Christ’s work on the cross.

‘And it shall be, when he is guilty in any of these matters, that he shall confess that he has sinned in that thing;” Lev 5:5

“As far as the east is from the west, So far has He removed our transgressions from us.”  Psalm 103:12

“Therefore, having been justified by faith, ^]we have peace with God through our Lord Jesus Christ,”  Romans 5:1
