Hebrews 11:24

By faith Moses. . . . chose.” Faith rests on promise; to faith, the promise is equivalent to fulfillment; and if only we have the one, we may dare to count on the other as already ours. It matters comparatively little that the thing promised is not given; it is sure and certain because God has pledged His word for it, and in anticipation we may enter on its enjoyment. Had Moses simply acted on what he saw, he would never have left Pharaoh’s palace.

But his faith told him of things hidden from his contemporaries, and these led him to act in a way which to them was perfectly incomprehensible.
