Our purpose is internal and eternal; our souls are also internal and eternal. God-given purpose has to do solely with man's soul. It first begins with the soul, then outward to one's calling. It is important to first develop the soul's purpose as the soul houses the character of the man. Man's character will affect positively or negatively man's calling. This is the process that the Holy Spirit takes God's people through as He did with Jesus in the wilderness to test His character; that is, His soul.
