"O that unbelievers would learn of faithful Abraham, and believe whatever is revealed from God, though they cannot fully comprehend it! Abraham knew God commanded him to offer up his son, and therefore believed, notwithstanding carnal reasoning might suggest may objections"

This quote by George Whitefield speaks with the power of faith and the significance of relying on God, even when we do not comprehend why He is asking us to do something. Whitefield is suggesting that we need to take a lesson from Abraham, who wanted to provide his boy, Isaac, although it didn't make good sense to him. Abraham trusted in God and followed His command, despite the fact that his carnal thinking might have suggested objections. Whitefield is encouraging us to believe God, even when we don't understand why He is asking us to do something. We ought to trust that God knows what is best for us and that He will provide us with the strength and guts to do what He asks.
