“Is any thing too hard for the LORD?” this was the question posed to Abraham and, in virtue of her questioning, surely to Sarah too, in Genesis 18:14.
The LORD had promised repeatedly that Abraham should have a son. He had just before promised again that the child of promise would be by Sarah. The LORD was going to show that He was faithful to His promise – Sarah would have a son, and did – Isaac.
But before Sarah conceived, her faith in the divine promise must needs be strengthened. She had, through long and painful experience of childlessness, come to see that, without the divine blessing, there could be no son. She was now, according to the flesh, past childbearing age. She recognised this, as did Abraham. However, God purposed that Isaac would be the child of this marriage union. His word was clear, “Sarah thy wife shall have a son.” (Genesis 18:10). As Sarah heard this she was amazed. How could this be? The answer to that question was given, “Is any thing too hard for the LORD?”
This question should encourage the Lord’s people in every generation. The world, the flesh and the devil, are all set against the advance of the gospel, within the soul of the individual believer and also the advance of the gospel in the world. But, in spite of all opposition, well might the people of God reflect, “Is any thing too hard for the LORD?”
John Calvin, in his comments on this chapter writes:
‘But if we thoroughly investigate the source of distrust, we shall find that the reason why we doubt of God’s promises is because we sinfully detract from his power. For as soon as any extraordinary difficulty occurs, then, whatever God has promised, seems to us fabulous; yea, the moment he speaks, the perverse thought insinuates itself, How will he fulfil his promises? Being bound down, and pre-occupied by such narrow thoughts, we exclude his power, the knowledge of which is better to us than a thousand worlds. In short, he who does not expect more from God than he is able to comprehend in the scanty measure of his own reason, does him a grievous wrong. Meanwhile, the word of the Lord ought to be inseparably joined with his power; for nothing is more preposterous, than to inquire what God can do, to the setting aside of his declared will.’ (J. Calvin, Commentary on Genesis Banner of Truth Trust 1965 p.476)
Note that immediately after this question, which begs its own most positive answer, the LORD affirmed again His promise to Abraham. “At the time appointed I will return unto thee, according to the time of life, and Sarah shall have a son.” There is a time appointed for every blessing that God purposes to bestow upon His own people and His own Church. But, like Sarah, we need our faith in the divine promise to be strengthened. The question, “Is any thing too hard for the LORD?” when applied with comfort by the Holy Spirit, can do this. May we think upon it, and the fact that God did give a son, even Isaac, so fulfilling His promise. In this way, we may be strengthened and encouraged to pray in faith and wait with patience.
