Through faith also Sara herself received strength to conceive seed, and was delivered of a child when she was past age…
I. WHEN GOD IS PLEASED TO INCREASE HIS CHURCH IN NUMBER, IT IS ON VARIOUS ACCOUNTS A MATTER OF REJOICING UNTO ALL BELIEVERS, and a subject of their daily prayers, as that which is frequently promised in the word of truth. This blessing of a numerous posterity is variously set forth, illustrated, and heightened.
1. From the root of it. It was one, one man, that .is, Abraham. Unto him alone was the great promise of the blessing Seed now confined. And he, though but one, was heir of all the promises.
2. From the consideration of the state and outward condition of that one, when he became the spring of this numerous posterity: "of him as good as dead." His body naturally was as useless unto the end of the procreation of such a posterity as if it had been dead.
II. GOD OFTENTIMES BY NATURE WORKS THINGS ABOVE THE POWER OF NATURE IN ITS ORDINARY EFFICACY AND OPERATIONS. So by weak and dead means He often produceth mighty effects.
(John Owen, D. D.)
