Selfishness is the cause of 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. Pride produces selfishness.
All selfishness is pride.
Doing things yourself, on your own, is a part of selfishness. Prayer is the opposite of doing things yourself. Let nothing be done through selfish ambition or conceit, but in lowliness of mind let each esteem others better than himself. 4 Let each of you look out not only for his own interests, but also for the interests of others. It takes faith to put others first.
