55:10, 11 God’s word is just as irresistible and effective as the rain and snow. All the armies in the world cannot stop them, and they accomplish their intended purpose. God’s Word never fails to achieve its aims:
So shall My word be that goes forth from My mouth; it shall not return to Me void, but it shall accomplish what I please, and it shall prosper in the thing for which I sent it.
55:10, 11 rain … snow … My word. Moisture from heaven invariably accomplishes its intended purpose in helping meet human physical needs. The Word of God will likewise produce its intended results in fulfilling God’s spiritual purposes, especially the establishment of the Davidic kingdom on earth (vv. 1–5).
55:10–11 As the rain and the snow cannot fail to nourish the earth, so God’s word of promise cannot fail to bring his people into the richness and fullness of eternal life. Human good intentions fail, but God’s promises succeed (cf. 40:6–8). The word of God not only describes a glorious future, it is God’s appointed means to create that future (cf. Ezek. 37:1–14).
55:11 It shall not return to me without success Yahweh’s word cannot fail to bring about the desired results (compare 40:8). The word of God contains very real power to accomplish His will. Creation happened through divine speech in Gen 1 (compare Psa 33:6, 9), and Yahweh brought life back into lifeless bones through the prophetic words of Ezekiel (Ezek 37:1–14).
55:10, 11 rain. The rain falls abundantly and of its own accord, and in a familiar but mysterious way produces plants and useful crops, evidently for the purpose of supplying people’s needs. The divine purpose in this is applied figuratively to the word of God in order to distinguish it from fallible human thoughts and plans. It also speaks of the Lord’s word as His decree by which He governs history. It never returns without accomplishing God’s sovereign purposes. Cf. 40:8.
55:11 It is the divine origin (or character) of God’s word, and not some magical power, which causes it to accomplish the purpose for which it is sent (cf. Heb. 4:12).
10–11 The declaration of vs 8–9 not only looks back to v 7 but on to vs 10–13, to shame us out of our small expectations. God’s thoughts are more far-reaching and more fertile, as well as higher, than ours. The comparison of his word with rain and … snow suggests a slow and silent work, transforming the face of the earth in due time. The reference is to his decree (cf. e.g. 44:26; 45:23) rather than his invitation or instruction, which can be refused (48:18–19; cf. the similar imagery to that of v 10 in Heb. 6:4–8).
55:10, 11 bring forth: For a similar reference, see 2 Cor. 9:10. God’s word is similar to rainfall; it produces fruit (Ps. 147:15–20). Just as water enlivens and strengthens a withering rose, God’s word produces life in the hearts of sinners.
55:10–11. Having spoken of the future time of blessing (the Millennium) and the salvation which leads to it, the Lord then assured believers that His Word … will accomplish what He says it will. His word is like rain and snow that water the earth and help give it abundant vegetation. In the Near East dry hard ground can seemingly overnight sprout with vegetation after the first rains of the rainy season. Similarly when God speaks His Word, it brings forth spiritual life, thus accomplishing His purpose.
