For what shall it profit a man if he gains the whole world but loses his soul.

Everybody wants to gets the "power" but the only exchange is the soul. A man will be useless without the soul that God gave, like what Nasus said "My brother has become hollow. Full of rage, but empty." A man can be like that without a soul. All power, but useless. Power is not the answer, it is trust. If you trust in Him, you don't need to lose your soul to be able to have power.
