The Word of God is powerful. The Greek word translated “powerful” in Hebrews 4:12 is energes, which is the source of our English word “energetic.” It’s translated “active” in some versions, and that’s a good translation. It speaks of something that is dynamic, operative, and effectual. The apostle Paul wrote to the believers in Thessalonica (1 Thessalonians 2:13): “For this cause also thank we God without ceasing, because, when ye received the word of God which ye heard of us, ye received it not as the word of men, but as it is in truth, the word of God, which effectually worketh also in you that believe.”
The Word of God always works effectually. It always accomplishes its intended purpose. In Isaiah 55:11, God says, “So shall my word be that goeth forth out of my mouth: it shall not return unto me void, but it shall accomplish that which I please, and it shall prosper in the thing whereto I sent it.”
Sometimes God’s purpose is rebuke and correction; sometimes it is instruction and edification. Sometimes it is blessing; sometimes it is judgment. The gospel is “the savour of death unto death” for some; for others, it is “the savour of life unto life.” Either way, the Word of God is effectual, productive, powerful. It always produces the effect God intends.
That’s why preachers ought to preach the Word instead of telling stories and doing comedy. That’s where the power for ministry resides: in the Word. It’s not in our cleverness or our oratorical skills. The power is in the Word of God. And our task is simple: all we have to do is make the Bible’s meaning plain, proclaim it with accuracy and clarity. And the Spirit of God uses His Word to transform lives. The power is in the Word, not in any technique or program.
