Without becoming weak in faith he contemplated his own body, now as good as dead since he was about a hundred years old, and the deadness of Sarah’s womb; yet, with respect to the promise of God, he did not waver in unbelief but grew strong in faith, giving glory to God, and being fully assured that what God had promised, He was able also to perform. Therefore it was also credited to him as righteousness (Romans 4:19-22).

We learn from Romans chapter four that "Abraham refused to consider the physical disabilities which seemed to make the fulfillment of God's promises impossible," writes F. B. Meyer. 

. . . He looked them all quietly in the face, as though taking into account all their significance and force. Then he looked to the promise; and after balancing one against the other, he decided absolutely and confidently that the Word of God must stand, however great and forbidding the difficulties in the way. He was fully persuaded that what God had promised He was able to perform.

Let us remember, then, that from the time we trust Christ--whatever may have been our present frailties and temptations--we are reckoned as righteous in the sight of God. Yes, and in addition, we may count on absolute deliverance from the power of sin. Do not look down, brooding over your weakness! Do not look back upon your past, strewn with failure! Look up to the living Christ! All the promises of God are yea and amen in Christ Jesus, 2 Cor. 1:20.

We stand in grace; we look for glory. Our standing is sure, although apart from our feelings. It is ours forever, through union with the living Christ. It is our admission to the home of God's elect (Through the Bible Day by Day, Vol. 6, pp.81-82).

Now not for his sake only was it written that it was credited to him, but for our sake also, to whom it will be credited, as those who believe in Him who raised Jesus our Lord from the dead, He who was delivered over because of our transgressions, and was raised because of our justification (Romans 4:23-25).
