God doesn't give diddly-squat to anybody.
However I learned mine from Buddhism.
Faith is a mental factor whose primary function is to remove doubt, doubt can only be experienced thru meditation, once "doubt" is realized, the awareness that it is there requires the strength of concentration to prevent it from becoming controlling. Only when this has occurred one can say they have experienced faith, albeit a very small amount of faith. Which is why in Buddhism, we practice complex visualizations to increase the chances of doubt, so we can develop our powers of concentration which make our faith stronger.

Only thru Faith can miracles be performed, not faith in something, just faith, a concentration of mind that removes doubt.
Matthew 17:20
He replied, "Because you have so little faith. I tell you the truth, if you have faith as small as a mustard seed, you can say to this mountain, 'Move from here to there' and it will move. Nothing will be impossible for you."
