God hath spoken once: twice have I heard this: that power belongeth unto God.
It is hard for us sons of the machine age to remember that there is no power apart from God! Whether physical, intellectual, moral or spiritual, power is contained in God, flows out from Him and returns to Him again. The power that works throughout His creation remains in Him even while it operates in an atom or a galaxy!
The notion that power is something God separates from Himself and tosses out to work apart from Him is erroneous. The power of nature is the Presence of God in the universe. This idea is woven into the book of Job, the Psalms and the Prophets.
The writings of John and Paul in the New Testament harmonize with this Old Testament doctrine, and in the book of Hebrews it is said that Christ upholds all things by the word of His power.
We must not think of the power of God as wild, irrational energy coursing haphazardly through the world like a lightning strike or a tornado. This is the impression sometimes created by Bible teachers who keep reminding us that dunamis, the Greek word for power, is the root from which comes our word “dynamite.” Little wonder that sensitive Christians shrink from contact with such a destructive and unpredictable force.
The power of God is not something God has: it is something God is! Power is something that is true of God as wisdom and love are true of Him. It is, if we might so state it, a fact of His being, one with and indivisible from everything else that He is. The power of God is one with God’s will and works only as He wills that it should. It is His holy Being in action!
62:11 Once God has spoken The psalmist uses a numerical saying—a literary device common in Wisdom Literature—as he looks to God’s promises (see Prov 30:18 and note).
62:11 once, Twice: It is a convention of wisdom literature to use a number and then raise it by one (Prov. 30:11–33). The point here is that David has heard the message with certainty.
62:11, 12 once, Twice: The ascending number emphasizes the truth of the following statement. To God belong power and mercy; He gives to each one as we deserve (see 1 Cor. 3:8).
62:11–12. The psalmist contrasted this with the fact that God has declared that the power is His. David heard God say two things: that He is strong and loving. So justice will be meted out to everybody. How much better then to find rest in the powerful God than in human devices.
11, 12 God has power (unlike man in his insubstantiality, 9) and unchanging love (unlike man’s deceitfulness, 9). Not only so, but his loving power is an active force of moral providence (12) whereby he ‘fully requites’ (reward). Therefore we can trust him for our welfare and against the works of our enemies.
