The lock-smith's great bunch of keys!

(Charles Spurgeon)

"He has given us His very great and precious promises!" 2 Peter 1:4
God's promises are precious, because they tell of exceedingly 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,
  promises of perfection.

In this blessed book you have . . .
  promises for time — and promises for eternity;
  promises for every condition every believer!

I sometimes liken God's promises to the lock-smith's great bunch of keys which he brings when you have lost the key of your chest, and cannot unlock it. He feels pretty sure that out of all the keys upon his ring, some one or another will fit, and he tries them with patient industry. At last — yes — that is it — he has loosened the bolt, and now you can get at your treasures!

In the same way, there is always a promise in the volume of inspiration, suitable to your present case.

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 every child of God can ever need!

"He has given us His very great and precious promises!"
