Charles Spurgeon Commentary Romans 4:18-20

"Who in hope believed against hope, to the end that he might become a father of many nations, according to that which had been spoken, So shall thy seed be. And without being weakened in faith he considered his own body now as good as dead (he being about a hundred years old), and the deadness of Sarah`s womb; yet, looking unto the promise of God, he wavered not through unbelief, but waxed strong through faith, giving glory to God," — Romans 4:18-20 (ASV)

Who against hope believed in hope, that he might become the father of many nations, according to that which was spoken, So shall your seed be. And being not weak in faith, he considered not his own body now dead, when he was about a hundred years old, neither yet the deadness of Sarah's womb; He staggered not at the promise of God through unbelief; but was strong in faith, giving glory to God:

Men seem to think that only workers can give glory to God; but there is more glory given to God by one drachma of faith than by a ton of works. After all, works usually generate conceit and pride in us. But faith lays itself low before its God, and gives to him all the glory. God is never more glorified than he is by the believing confidence of his people when difficulties seem to come in the way.

He was strong in faith, giving glory to God.
