The degree of faith is determined by the degree to which the obedience is justified by God himself (his character) versus anything else.
The world defines faith incorrectly as believing without having a reason.
Those with more light than most define it as doing what you have reason to do.
The purest of faith—the one that opens the door to the greatest of God’s blessings, which can be had in no other way—is found in those feelings and actions whose reason is God himself.
