Better understanding does build better faith. “For unto whomsoever much is given, of him shall be much required” (Luke 12:48 KJV). When do we have enough understanding to believe God? The LORD knew that Gideon was not guilty of the sin of unbelief though he put out the fleece for a sign (Judges 6). Zacharias did not believe the angel’s announcement about the coming birth of John the Baptist (Luke 1:20), so God struck him mute. We have enough understanding when we know what we should do. For “him that knoweth to do good, and doeth it not, to him it is sin” (James 4:17 KJV). We need to practice arriving at a forthright conclusion and acting on it. The best course is straightforward.
