The Apostle is careful to point out the wide and essential difference between the oath of God and the oaths of men. “For men swear by the greater;” that is, they call upon God, as the Almighty, to destroy them if they are uttering what is false. They imprecate a curse upon themselves. If they have sworn to a falsehood, and if the imprecation falls on their heads, they perish, and the matter ends. And yet an oath decides all disputes between man and man.[114] Though they appeal to an Omnipotence that often turns a deaf ear to their prayer against themselves; though, if the Almighty were to fling retribution on them, the wheels of nature would whirl as merrily as before; though, if their false swearing were to cause the heavens to fall, the men would still exist and continue to be men;—yet, for all this, they accept an oath as final settlement. They are compelled to come to terms; for they are at their wits’ end. But it is very different with the oath of God. When He swears by Himself, He appeals, not to His omnipotence, but to His truthfulness. If any jot or tittle of God’s promise fails to the feeblest child that trusts Him, God ceases to be. He has been annihilated, not by an act of power, but by a lie. We have said that the oath met, not the weakness, but the strength, of Abraham’s faith. If so, why was it given him? _First_, it simplified his faith. It removed all tendency to morbid introspection and filled his spirit with a peaceful reliance on God’s faithfulness. He had no more need to try himself whether he was in the faith. Anxious effort and painful struggle were over. Faith was now the very life of his soul. He could leave his concerns to God, and wait. This is the thought expressed in the word “enduring.” _Second_, it was a new revelation of God to him, and thus elevated his spiritual nature. The moral character of the Most High, rather than His natural attribute of omnipotence, became the resting-place of his spirit. Even the joy of God’s heart was made known and communicated to his. God was pleased with Abraham’s final victory over unbelief, and wished to show him more abundantly[115] His counsel and the immutability of it. “The secret of the Lord is with them that fear Him, and He will show them His covenant.”[116]
