The life we live today has become more and more selfish with everyone seeking self satisfaction rather than please God. We have to understand the art of loving others, and thinking about others before ourselves. If Jesus thought more about himself, he won’t have gone to the cross for us. Jesus said, if we focus on doing good deeds towards others, we are actually doing them for him. It is ok to think about yourself or care for yourself, but when it becomes the most important thing, then it becomes selfishness, which is a sin before God. Remember do your best at showing love and putting God first, he will reward you with your own desires.
Mark 8:35-38, John 15:13
