The Word That Will Not Return Void - Isaiah 55:10-11 Isaiah 55:10–11 reveals the divine certainty, purpose, and power of God's Word, which, like rain and snow from heaven, never returns void but accomplishes exactly what God intends. Rooted in the unchanging authority of God, the Word is not a human utterance but a sovereign, inspired revelation that carries divine efficacy, ensuring it will not fail in its mission to convict, convert, and build the people of God. Though results may be unseen or delayed, the Word operates with unstoppable effectiveness, transforming hearts across generations—even through sermons preached decades ago and heard in unexpected moments. This truth calls believers to reverence, confidence, and perseverance in proclaiming Scripture, trusting that God's purpose is fulfilled not by human skill but by the eternal power of His Word, which ultimately glorifies Him and brings eternal life to those who hear it.
