For all the promises of God in Him are Yes, and in Him Amen, to the glory of God through us. – 2 Corinthians 1:20

Have you ever noticed, dear friends, how much we live upon the promises of our fellow-men?…The commonest form of a promise is a bank note; and it is worth while to observe how much a bank note is made after the model of God’s promises. How does the wording of this bank note run? It is headed, “Bank of England;” and it begins, “I promise.” You take this note readily enough instead of five golden sovereigns, because you read on it, “I promise to pay the bearer;” and God’s promise is payable to “the bearer.” Whoever has the promise in his possession, whoever has faith enough to lay hold of God’s promise, may read it in this way: “I promise to pay the bearer.” I remember when I first snatched at one of God’s precious promises; I could hardly hope that I had any right to it, for I felt myself so utterly unworthy, but I snatched it up, and ran with it to the Bank of Faith, and as soon as I presented it, I received its full value. God always honours His own promises; here is one: “Him that cometh to Me I will in no wise cast out.” Go to Him with that gracious message, and it shall be fulfilled to you whoever you are. The note says, “I promise to pay the bearer.”…What does it now say on the bank note “I promise to pay the bearer on demand.” That is how all God’s promises run: “on demand.” It is worthy of note that, in the olden time, when the Lord had made many promises to His people, He added, “I will yet for this be enquired of by thee, house of Israel, to do it for them; “as though the fulfillment of the promise was delayed until it was asked for. No doubt many of God’s great and precious promises are not realized by you and me because they are not presented to the Lord as we should take a note to the bank to get it cashed. We do not enquire of God as much as we ought. ~ C.H. Spurgeon
