1 Timothy 1:13 although I was formerly a blasphemer, a persecutor, and an insolent man; but I obtained mercy because I did it ignorantly in unbelief.
Jesus did not go round trying to blame everyone for doing anything wrong; instead He tried to come and look for the lost people and make them whole again!
Trying to blame other people when we are to blame ourselves is not going to help anyone. It will stop us from living our lives fully with God.
We end up doing what we can in the time we are given; and that is what God requires us first of all.
Live a full life with Christ and not half a good life without Him!
