"...He has given us His very great and precious promises..." 2 Peter 1:4
God's promises are precious because they tell of exceeding great and precious things. We have promises in the Bible which time would fail us to repeat, which for breadth and length are immeasurable. They deal with every great thing which the soul can need: promises of pardoned sin, promises of sanctification, promises of teaching, promises of guidance, promises of upholding, promises of ennobling, promises of progress, promises of consolation, and promises of perfection. In this blessed book you have.... promises of the daily bread of earth; promises of the bread of life from heaven; promises for time; promises for eternity.
You have so many promises, that all the conditions and positions of the believer are met. I sometimes liken the promises to the locksmith's great bunch of keys, which he brings when you have lost the key of your treasure chest, and cannot unlock it. He feels pretty sure that out of all the keys upon the ring some one or other will fit, and he tries them with patient industry. At last! yes! that is it, he has moved the bolt, and you can get at your treasures! There is always a promise in the volume of inspiration suitable to your present case. Make the Lord's promises your delight and your counselors, and they will befriend you at every turn.
Search the Scriptures, and you shall meet with a promise which will be so applicable to you as to appear to have been written after your trouble had occurred! So exactly will it apply, that you will be compelled to marvel at the wonderful tenderness and suitableness of it. As if the tailor had measured you from head to foot, so exactly shall the garment of the promise befit you. The promises are precious in themselves.... from their suitability to us, from their coming from God, from their being immutable, from their being sure of performance, and from their containing wrapped up within themselves all that the children of God can ever need.
