Beeke and Smalley on God's Power

Beeke and Smalley write,

God's sovereignty calls us to trust in the promises. The eye of the flesh cannot see how it is possible for God's promises to come true, but the eye of faith looks to the Lord omnipotent. It seemed ridiculous that God would give old Abraham and barren Sarah a son, but he gently admonished them, "Is any thing too hard for the LORD?" (Gen. 18:14). Whatever dangers you may face, believe that God is able to sustain you in them or rescue you from them. Let those in covenant with God rejoice that their Lord is almighty; they have a friend who can do anything. A hearty confidence in God's infinite power is requisite for us to trust his promises, for we must be, like Abraham, "fully persuaded that, what he had promised, he was able to perform" (Rom. 4:21).
