Hebrews 11:12

These words acquaint us with that gratuitous remuneration and gracious reward which God gave Abraham and Sarah, as the fruit of the faith, namely, the blessing of. numerous posterity; there sprang of them, and both of them, as good as dead, with reference to the procreation of children,. numerous issue like the stars of heaven, and the sands of the sea.

Hence learn, That the God of nature, at his own pleasure, works things above the power of nature in its ordinary efficacy and operations; by weak and dead means he often produces mighty effects.

Learn, 2. That whatever difficulties and oppositions lie in the way of the accomplishing of God's promises, they shall have an assured accomplishment on God's part, if faith be kept up in lively exercise on our part.
