Nevertheless, He saved them for His name’s sake, that He might make His mighty power to be known. – Psalm 106:8

You remember how (the Israelites) sang: “Then the dukes of Edom shall be amazed; the mighty men of Moab trembling shall take hold upon them; all the inhabitants of Canaan shall melt away. Fear and dread shall fall upon them; by the greatness of thine arm they shall be as still as a stone; till Thy people pass over, O Lord, till the people pass over, which Thou hath purchased. Thou shalt bring them in, and plant them in the mountain of Thine inheritance, in the place, O Lord, which Thou hast made for Thee to dwell in, in the Sanctuary, O Lord, which Thy hands have established.” They felt quite sure of conquering the land and chasing out the foe. They were so strong in faith, that they thought they should never again mistrust the Lord, whose right hand was so glorious in power. The exultant women who followed Miriam never suspected that they could doubt the Lord, whose right hand had dashed in pieces the enemy. One of them would probably have said, “As for our enemies, the depths have covered them, there is not one of them left. I shall never fear again. I have attained full assurance and perfection, and I shall never again mistrust the Lord.” Yet these were the people who speedily murmured for want of bread, until the Lord heard them, and was grieved. I dare say the men of the Red Sea said, each one, “My mountain standeth firm, I shall never be moved”; and yet in how brief an hour were they challenging the faithfulness of Jehovah and questioning His power to give them bread in the wilderness! Lord, what is man? We distrust providence, we suspect grace, and we question the Lord Himself; and all this after the Lord had made our assurance doubly sure. We are sad creatures, and yet the Lord does not cast us away; for it is written, “Nevertheless He saved them for His names sake, that He might make His mighty power to be known.”

Admire the patient faithfulness of our God. Jehovah, though provoked, still loves His people. Admire His love to ourselves; and especially that He should entertain such constancy of affection towards such wayward, fickle, unreliable souls as we are! ~ C.H. Spurgeon
