The Bible says, that blessed are the merciful for they will receive mercy and proverbs says a cruel man does himself harm. I can think of examples of both.
As a young Christian, I felt deep sympathy for those who suffered and within 6 years, my tribulations ended.
A guy I knew who judged me for my emotional weakness and mental frailty and refused to let me receive prayer from his prayer group when I was suffering, has been going through tribulations for over 18 years, and while I do not need people to pray for me because I do not have problems, he constantly needs people to pray for him, because his problems are so many.
I tried to share my understanding of God with others and now my faith is easy because I see God’s mercy while he refused to share his knowledge of the bible with weak believers and 18 years later, he’s just as ignorant about the meaning of scripture and religion as he was 18 years ago.
I was willing to acknowledge I sinned and humble myself and God shows me all the time things I can do to improve myself while he is still righteous in his own eyes and just as ignorant about his flaws now as he was 18 years ago.
He used to tell me your progress in life is determined by how you treat others.
He has money and a beautiful wife, but he’s destined to go to hell after he dies, because in his striving, he forgot the mercy of God, of the son and of the Spirit.
