This is the key right here. As far as Christ is concerned, they're forgiven and forgotten. Satan, however, will use anything he can to drive a wedge between us and Christ and place a stumbling block in our path -- and dredging up guilt over old sins is right in his wheelhouse.
IN THE NAME OF THE LORD JESUS CHRIST, SATAN BEGONE!
People can be in the attitude of the spirit of ol Ha’Satan sometimes; they can accuse you of something you did in the past, and bring it up again. You yourself can do it to your own self by your own thoughts within your soul, but Eg did make a great point.
Hebrews 8:12 For I will forgive their wickedness and will remember their sins no more.”
There must be something though that does help with going to Yahava and confessing our faults not to keep us on the hamster wheel of repentance however something where you and Yahava are working together to keep help you by the spirit to have joy, peace, and things like that as well.
Luke 11:13 If you then, though you are evil, know how to give good gifts to your children, how much more will your Father in heaven give the Holy Spirit to those who ask him!”
Jesus states here about going to the Father and asking him for help by the spirit.
1 John 1:9-10If we confess our sins, he is faithful and just and will forgive us our sins and purify us from all unrighteousness. If we claim we have not sinned, we make him out to be a liar and his word is not in us.
Thank you for your comment Jim, and Eg.
