I believe it is very important for every believer to have an understanding of and conviction from the Holy Spirit through the scriptures concerning the total depravity of all men, before a holy God, but at the same time to realize that one soul in the eyes of God is worth more than to gain the whole world (Mt 16:26)...
26 For what is a man profited , if he shall gain the whole world, and lose his own soul?
This is the depravity of man, which is to possess and gain all things that this world could provide, yet lose their own soul and become lost to eternal life provided by their Maker through the Lord Jesus Christ. The total depravity of being so blind that they can not discern or perceive where they will end up even though they possess all things and have need of nothing. They never see or realize that it has been the goodness of God that has provided the air they breath and the hand of God the food they and their family have to eat. They never acknowledge God for their existence and for how God has created them in the womb and given them life through conception. If this is the perception of the man in the depravity of his unbelief, what should ours be that have believed? Are we to be as arrogant and live in the self conceit of ignorance as those that have no fear of God?
