To change ourselves for the better as a person has to be one of the most difficult things for us to do. Even though we know our faults and sins and wish to change, it's no easy task. Otherwise, the world, the nations, our societies, and all families would be in much better shape. It is the ego, the pride, that grips us. I believe that in general, men are more wont to be their own master than women. The Lord God is the only one who can fundamentally change us – after all he is our creator. But we still need to yield our heart to him first. Again, humility is a must to get the ball rolling.
