“For it is by grace you have been saved, through faith; and this is not from yourselves, it is a gift of God- not by works, so that no one can boast.” Ephesians 2:8-9
All of mankind has been given the same measure of grace no matter how much or how little we do. All sin (that’s ALL, every single person’s) past and present sin was covered by the blood of Jesus at the Cross of Calvary and there is nothing too big or too small that the cross won’t cover.
Accepting this free gift is the only requirement. You were not ever expected to live a sinless life, you just simply couldn’t.
