(Proverbs 11:17 KJV) The merciful man doeth good to his own soul: but he that is cruel troubleth his own flesh.
There is such a things as a “cruel man” (394). They are not just misunderstood. You may not like it, but it is true. All of your education in secular schools may scream, “No!” It is still true.
There are people in the world who get their kicks by causing pain and enjoy seeing others suffer. We need to learn to admit this so that we can deal with them. It doesn’t do any good to deny that disease exits. It doesn’t make you warm to claim there is not snow on the ground just because you don’t want to shovel it.
So? Learn to deal with reality. God is love. The world needs that love but most tend to reject it. We are still called to turn the other cheek and walk the extra mile. Go for it but don’t expect people to thank you.
