God's Word Will Not Fail
Isaiah 55:11 (ESV) … “so shall my word be that goes out from my mouth; it shall not return to me empty, but it shall accomplish that which I purpose, and shall succeed in the thing for which I sent it.”
God’s Word cannot fail to bring about the desired results. The Word of God contains very real power to accomplish His will. Creation happened through divine speech in Genesis 1, and God brought life back into lifeless bones through the prophetic words of Ezekiel 37:1–14.
Furthermore, God’s Word is seed (Luke 8:11). Just as the rain and snow are never wasted but accomplish His purposes, so His Word never fails. “The Word of our God shall stand forever” (Isa. 40:8). We never know how God will use even a casual word of witness to plant and water the seed in somebody’s heart.
A.W. Tozer reminds of the power and authority of God’s Word in telling us the following: God’s Word is both our terror and our hope; it both kills and makes alive. If we engage it in faith, humility and obedience, it gives life, cleanses, feeds and defends. If we close it in unbelief or ignore it or resist it, it will accuse us before the God who gave it. It is the living Word of God, coming like a fierce man of war with great power, and you and I dare not resist it, and we dare not argue it down.[1]
The truth concerning God’s Word, is that it is both our terror and our hope. It has both the power to kill and make alive. If we engage it in faith, humility and obedience, it gives life, cleanses, feeds and defends. If we close it in unbelief or ignore it or resist it, it will accuse us before the God who gave it. It is the living Word of God, coming like a fierce man of war with great power, and you and I dare not resist it, and we dare not argue it down.
