Where is this found in scripture? I understand satan has the power to tempt us (as he did with Jesus) when God allows it. Where is it ever stated in scripture that satan has the power the authority or ability to accuse us directly? The only reference found in scripture dealing with satan and a believer in Christ is that he accuses the brethren before God himself as described in Revelation. Satan has no true power over any Christian nor does he have any claim to overtly control our thoughts.
I suggest reading Romans 8:28-39. I wont quote it for brevity.

Paul also stated in Corinthians that darkness can have no fellowship with light. Although Paul used the reference in regards to marriage, the principle he spoke of was a spiritual one that built on parables Christ used to teach about the inner workings of our heart/soul/spirit.
I was also raised in various charismatic/non-denominational churches and taught many times over how the devil was responsible for practically every bad thing that befell a believer. I was also taught that any remembrance of past sins was of the devil because “Christ forgot it” therefore it must come from him. I have found those teachings to be irresponsible nonsense at worst and an excuse for our own actions at best. The only one who has dominion in our heart/mind/soul (if we are Christians) is Christ.
Our own physical minds are not purged of our sins for a reason. If we forget our mistakes, then we will surely repeat them. Part of the “suffering” we experience as Christians is knowing how/when we fell short. We have to live with the knowledge and consequences our sin caused. That is not something that God pardons when we fall short, only the eternal consequences that sin brought to our life are forgiven and forgotten.
When we as Christians allow our minds to revert back to our sinful nature rather than the mind of Christ, we can, should and will be tormented by our past. I believe this to be a good thing for us. When we remember our past, hopefully our response should be to refocus on Christ as the Holy Spirit within us brings conviction when we stumble.
