Here is a fine excerpt from a chapter on God’s Power, written by John Frame, in The Doctrine of God. It brought me to pause and praise our mighty Lord.
Redemption itself contradicts all human expectations. It is God’s mighty power entering a situation that, from a human viewpoint, is hopeless. God comes to Abraham, who is over a hundred years old, and to Sarah, far beyond the age of childbearing, and He promises them a natural son. Sarah laughs. But God asks, “Is anything too hard for the LORD?” (Gen. 18:14). God’s omnipotence intervenes, and Isaac is born. The omnipotence is the power of God’s covenant promise. The Hebrew text literally reads, “Is any word of God void of power?” God’s powerful word comes into our world of sin and death and promises salvation. Isaac will continue the covenant, and from him, in God’s time, will come the Messiah, who will save His people from their sins. When the Messiah comes, He will be born, not to a barren woman like Sarah, but to a virgin — an even greater manifestation of God’s omnipotence. So to Mary the angel echoes God’s promise to Abraham: “Nothing is impossible with God” (Luke 1:36).
So God’s word never returns to Him void (Isa. 55:11). It is His omnipotence, doing for us what we could never do for ourselves. Apart from God’s power, we could expect only death and eternal condemnation. But he brings life in the place of death. So the resurrection of Christ becomes a paradigm of divine power in Ephesians 1:19-23. A God who can raise people from the dead can do anything. He is a God who is worthy of trust.
