Discovery of talents and gifts will aid the discovery of personal purpose and unique vision, but they are not identical to the grand, great, general purpose of all human existence. We all know talented and gifted people who are directionless!
Remain in Me, and I will remain in you. For a branch cannot produce fruit if it is severed from the vine, and you cannot be fruitful unless you remain in Me. - The Bible (John 15:4)
