What do kind thoughts do for you? Keeps you focused, lets you think all the good things about a situation. Kind thoughts bring positive energy into play. God wants us to think of others kindly, not dwell in the bad stuff. When the bad thoughts come in, we must learn to say, this will not consume me and I am not spending time on it.
When you think kindly about people you also give away that sense of a nice personality and people are attracted to that. God wants only the best thought to be part of your everyday life. Prayers are great kind thoughts expressed to God~!
