Faith is not intelligent understanding, faith is deliberate commitment to a Person where I see no way.
Are you debating whether to take a step in faith in Jesus or to wait until you can see how to do the thing yourself? Obey Him with glad reckless joy. When He says something and you begin to debate, it is because you have a conception of His honour which is not His honour. Are you loyal to Jesus or loyal to your notion of Him? Are you loyal to what He says, or are you trying to compromise with conceptions which never came from Him? “Whatsoever He saith unto you, do it.”
