God permits evil because if He didn't, it would mean the end of our free will. God allows us to choose our destiny, that's the point of this tiny speck of dust we call planet earth. But the price of that freedom means the existence of evil. The good news is that our life on earth is brief, and the world is but a stage for man to make choices. That's the point of our human conception---it makes possible a harvest of souls who freely choose to seek God, or to reject God. The free choice has a built-in consequence, thus the responsibility of our destiny lies squarely upon our free choices, which God will eternally respect. A man can be coaxed, warned and pleaded with not to drink poison because of the horrible consequences, but the man is free to drink poison nonetheless.
What we do with our intellect, free will, and out time is our responsibility. Death simply marks the moment a soul enters the eternal state. A soul is either in union with God, or separated from God for all eternity. The consequence of those who choose a path of evil, is that it blinds the intellect. Thus there are many smart people who are proud of all the facts they can remember, yet they are not very wise. In fact, often time they are the dumbest people because they miss the very point of their existence.
Does a person with schizophrenia unable to take care of himself....or a person with severe mental retardation have free will?
