(Sorry, I sent you Saturday’s yesterday so I will send you Friday’s today.)
“If anyone says, ‘I love God,’ yet hates his brother, he is a liar. For anyone who does not love his brother, whom he has seen, cannot love God, whom he has not seen.”
Jealousy and hatred are very much akin. Are there people you are jealous of? Do they have a position you want, and so you say and do things to undermine their character or work, so you can get their position? Do you have a position you love, and there is a new person who could perform better, so you undermine that person’s ability in order to protect your position?
God eliminates jealousy this way: What you accomplish in public isn’t as important to him as what you accomplish in private. Jesus said those who receive acclamation by people already have their reward, so will not be acclaimed by God (Matthew 6:1-5, 16-18). As much as it goes against human nature, prefer to do your good deeds in private, and God will reward you openly.
