God Is Not Powerless

Here is an age of wonders beginning, and therefore be not surprised: here is one among thy own relations truly great, though not altogether so great as this; it is usual with God to advance in working wonders. Greater works than these shall ye do. Though Elisabeth was, on the father's side, of the daughters of Aaron, yet on the mother's side she might be of the house of David, for those two families often intermarried, as an earnest of the uniting of the royalty and the priesthood of the Messiah. This is the sixth month with her that was called barren. This intimates, as Dr. Lightfoot thinks, that all the instances in the Old Testament of those having children that had been long barren, which was above nature, were designed to prepare the world for the belief of a virgin's bearing a son, which was against nature. And therefore, even in the birth of Isaac, Abraham saw Christ's day, foresaw such a miracle in the birth of Christ. The angel assures Mary of this, to encourage her faith, and concludes with that great truth, of undoubted certainty and universal use, For with God nothing shall be impossible, and, if nothing, then not this. Abraham therefore staggered not at the belief of the divine promise, because he was strong in his belief of the divine power, Rom. 4:20, 21. No word of God must be incredible to us, as long as no work of God is impossible to him. - Matthew Henry
