I love mankind as a whole, but when it comes to individual people I have the hardest time with it. A lot of the people I am surrounded by in the workplace I absolutley cannot stand. Public places I detest a lot of other people too. I guess you could say I skirt a little bit with misanthropy.
So how does one reverse a heart of stone?
B.C. in my life, when I started to realize my spiritual condition, I used to pray to God to help me see others through His eyes.
Now I am a practicing Christian, I simply put them on my prayer list and pray everyday for them along with everyone else on the list. God helps us, and will help the other person too if they want.
I also practice looking past things I know will bother me if I allow it, so I try to catch the thought as it generates and brush past it as a form of mental discipline. Still working on that one. Sometimes we are tempted with thoughts, absolutely bombarded, and that's when I go to confession and that helps too.
I had a completely severe over the top week of thought bombardment prior to baptism. I literally felt my heart turn to stone during prayer, over one comment someone said to me at church. I was tempted in all my weak areas the week or two prior. Someone, I have no idea who, even texted me a photo of the satanic bible. It was like running a gauntlet.
The more I see my own sin, the less I struggle with that issue. I am still learning in this area myself, maybe it is something we all work on our entire lives, or don't as we will.
People do evil stuff, sometimes even unwittingly, but ultimately God's love prevails (it is finished, complete), and we pray He will prevail in our own heart.
