Through his conscience a man may choose between the 'good' or 'evil' from the tree of the knowledge of good and evil. The result of either choice is death, is it not?
Through the Holy Spirit, a man may choose to be direct by God or by his own ways. This is a real choice between Life and death, is it not?
"O LORD, I know that the way of man is not in himself: it is not in man that walketh to direct his steps." Jerem 10:23
"Trust in the LORD with all thine heart; and lean not unto thine own understanding.
In all thy ways acknowledge him, and he shall direct thy paths." Prov 3:5-6
