I will stand upon my watch, and set me upon the tower, and will watch to see what He will say unto me, and what I shall answer when I am reproved. And the Lord answered me, and said, Write the vision, and make it plain upon tables, that he may run that readeth it. For the vision is yet for an appointed time, but at the end it shall speak, and not lie: though it tarry, wait for it; because it will surely come, it will not tarry. Behold, his soul which is lifted up is not upright in him: but the just shall live by his faith." Hab.2:1-4

...to wish God to conform to our rule is extremely preposterous and unreasonable: and there is no place for faith, if we expect God to fulfill immediately what He promises. It is hence the trial of faith to acquiesce in God’s Word, when its accomplishment does in no way appear. As then the Prophet teaches us, that the vision is yet for a time, he reminds us that we have no faith, except we are satisfied with God’s Word alone, and suspend our desires until the seasonable time comes, that which God Himself has appointed. The vision, then, yet shall be. But we are inclined to reduce, as it were, to nothing the power of God, except He accomplishes what He has said: “Yet, yet,” says the Prophet, “the vision shall be;” that is, “Though God does not stretch forth His hand, still let what He has spoken be sufficient for you: let then the vision itself be enough for you; let it be deemed worthy of credit, so that the Word of God may on its own account be believed; and let it not be tried according to the common rule; for men charge God with falsehood, except He immediately yields to their desires.
