The most painful thing in life is for you to have soo much abilities on the inside of you and die without manifesting these abilities. How will you feel as a president, a man of God, a believer, a doctor, lawyer or a rich person who couldn't use his or her opportunities to change situations in your family, country and in the world at large but turned out to chase after selfish ambitions ? Hebrews 9:27 And as it is appointed unto men once to die, but after this the judgment.
