"Is any thing too hard for the LORD? At the time appointed I will return unto thee, according to the time of life, and Sarah shall have a son." (Genesis 18:14)
This rhetorical question posed to Abraham by the Lord was in response to Sarah's doubts concerning His promise that they would have a son. It would, indeed, require a biological miracle, for both were much too old for this to happen otherwise. With God, however, all things are possible, and He can, and will, fulfill every promise, even if a miracle is required.
This same rhetorical question was asked of the prophet Jeremiah. "Then came the word of the LORD unto Jeremiah, saying, Behold, I am the LORD, the God of all flesh: is there any thing too hard for me?" (Jeremiah 32:26-27). The One who created all flesh, who raises up kings and puts them down, could surely fulfill His promise to restore Israel to its homeland when the set time was come.
But Jeremiah had already confessed his faith in God's omnipotence. "Ah Lord GOD! behold, thou hast made the heaven and the earth by thy great power and stretched out arm, and there is nothing too hard for thee" (Jeremiah 32:17). The God who called the mighty universe into being would not fail to keep His promise and fulfill His will.
Actually, the word translated "hard" in these verses is more commonly rendered "wonderful," or "marvelous," or an equivalent adjective, referring usually to something miraculous that could only be accomplished by God. For example, "marvelous things did he . . . in the land of Egypt" (Psalm 78:12). "For thou art great, and doest wondrous things: thou art God alone" (Psalm 86:10).
The first occurrence of the word (Hebrew pala), however, is in our text for today. There is nothing—no thing—too hard for the Lord, and we should never doubt His word! HMM
