In contribution to The above question, here is my thought on the topic. From the scripture reference;
1 John 5:16 If anyone sees his brother sinning a sin which does not lead to death, he will ask, and He will give him life for those who commit sin not leading to death. There is sin leading to death. I do not say that he should pray about that.

If we keep sinning intentionally in the name of grace, we can frustrate the grace of God upon our lives According to Romans 6:1. And Hebrews 10:26-27. No more sacrifice can be made for a spiritually matured believer who continues willfully on the path of sin.
But when we make mistakes and unwillingly. There is forgiveness of sin. That was why Jesus told Peter in Mathew 18:21-22. to forgive seventy seven times seven times.
