I'm going to bite... and respond to this in an honest and transparent way...
I think you are asking this? Does trauma/abuse/suffering/devastation affect how someone responds to or initiates into sin in their lives.. and does it numb or remove the need to repent? ( making one just act out and not care )... I probably made this more complicated than it needed to be... but I am going to answer on the premise that this is what you are asking.
I will speak openly and honestly about myself... which is something I don't usually do.. but I am feeling festive today.
I am 57 years old... and have been a Christian for approximately 19 years... If I was to receive a REPORT CARD from some Christians...
I would surely get a failing grade because I have been a slow learner. The problem is that I was given very bad counsel in those beginning years and I was made to think that God was angry and out to get me... I was also told that depression ( which I have suffered with for 40 years ) was a demon... so... I gave up before I even began... because I hated myself... and saw no use in trying when I had no hope of succeeding.
If someone had told me in the beginning WHO I WAS in CHRIST... and that GOD LOVED me... WAS FOR ME... and NOT against me... I believe I would be much farther along than I am now... Thankfully in the mean time... God has done miraculous work... healing the very deep and inner parts of my broken heart... the parts that no one can see...
I believe HE understands that I have had a very difficult life... He understands that I was abandoned as a child by my father.. and that he later hung himself... He understands that my mother was very mentally ill and an alcoholic... with many suicide attempts... and that she did not have the ability to nourish me as a child.. therefore I grew up raising myself and TRUSTING NO ONE.... He understands that I have had a difficult time even trusting Him. Over these twenty very LONG and painful years... I have been convinced that HE understands and LOVES me... He continues to be ever so tender and gentle with me... and I am grateful for that... He knows I am fragile... therefore He will NOT crush me.
Does trauma affect sinning and repenting? YES it does... and I believe God understands this only too well... Trauma affects how one sees themselves... and how they see God... If someone is not there at the very beginning of someone's salvation... to point them in the right direction... ( showing them who they are in Christ... and what forgiveness of their sins means )... they are just as lost when they get saved as they were when they were not... making things much more difficult to figure out.
Sadly... there are so many poisonous doctrines out there that becoming a Christian can be a very harsh and overwhelming experience... and that is sad to me.
Repenting for me is something that I need to do so that I can be right with God... I don't think about sinning... I just know in my heart when I have done something wrong... I need to fix it so that I can be at PEACE. I am grateful that His mercies are new every morning... I depend on that promise to get me through my day.
WOW.... What a confession this has been. My two cents worth for a Saturday... If I went off topic... I am sorry.
When I was a student I assumed I could climb a climbing wall. I climbed trees, 40ft in the air, hang over over hangs no problem.
I got 10ft up a climbing wall and froze. Something about the environment freaked me out. My kids got into climbing on a climbing wall and so I went along. I had to concentrate and remember what it would look like looking down 30ft up with only a few hand holds. I could be safe, no problems, I could know I was safe, but if I did not prepare to deal with my fears and weaknesses I was lost.
Jesus teaches very similarly. We know our strengths and weaknesses, what helps and what destroys, yet for a time the weak things appeal. We even get involved, and find they change us. Repentance is seeing the truth and walking the straight path because we know it works, we know what we need, and when it kicks in, it is so real.
Jesus is all in all. Jesus is the healer, the one who teaches us the way of true emotional, physical life. I grew up in a family where none spoke to who they were, but pretended to be something else. No one knew each other, but pretended they did. There was such confusion the family thought it was sorted and functioning, but it was just a stage, where each did not know whether they were loved or to love really. It is called a schizophrenic family, and the generations had a history of illness. What I did know was Jesus was real, and spoke emotional reality, and every step towards Him brought light into my life. Yes I was depressed, alone, empty, without an anchor or belonging, but Jesus had something that transcended this. I now stand with a loving wife, three grown up kids in stable loving relationships and praising the Lord.
And the cornerstone is repentance, being honest with oneself, this aloneness and lostness, and the need, an ocean of need, that He can fill.
Love is the word that is both eternal, is God himself and is blazing righteousness. But only the pure in heart get to see this.
The words of scripture only fall into place when we bow at His throne and the Holy Spirit works deeply in us. So much appears like a list of rewards, but is actually a statement of what we need to become, out of choice, out of love, out of our walk, out of His word living within our hearts. And most of all out of facing our fears and working within our limitations. Knowing our frailty, is no illusion, we are all unbelievably fragile. Our strength is always an illusion. We are the strength Christ in us makes us become.
God bless you
