Everyone is Given a Measure of Faith. It is what each one does with that measure that makes the difference. Faith must be used, or there is no benefit to having it.

Romans 12:3. For I say, through the grace that has been given to me, to everyone who is among you, not to think too highly of yourselves beyond which it is necessary to think, but to think to put a moderate estimate of yourself, in the same manner as God divided to each a measure of faith.
