Pride and selfishness always go together. A truly humble person cannot be selfish. Pride produces selfishness. Pride is hidden but manifests as selfish acts. Where there is jealousy and selfishness, there is also disorder and every kind of evil.
Selfishness causes all evil.
All evil proceeds from selfish actions. Selfishness is the only manifest problem, but pride feeds it. Dealing with the root cause of the problem is the only lasting solution. Submitting to the Lordship of Jesus Christ, and realizing we are not the center of the Universe, is the answer. Without Jesus, you can do nothing.
