I have had some experience with pharmaceutical sales, and one of the questions asked by doctors about a drug is whether or not it loses efficacy over time. In other words, does the medication work well at first, but over time loses its effect on the condition that is being treated? What I want to talk about is something that definitely does not lose efficacy over time. In fact, it is still the most powerful cure in the universe. It is the blood of Jesus!

The apostle Peter talks about the blood this way:

knowing that you were not redeemed with corruptible things, like silver or gold, from your aimless conduct received by tradition from your fathers, but with the precious blood of Christ, as of a lamb without blemish and without spot. (I Peter 1:18, 19 NKJV)

The blood is something precious. Its value is far above that of silver or gold. This blood is the cure for the most deadly disease in existence. It is used to bring spiritually dead people back to life! You may wonder if we baptize dead people. I would say that, yes, we do. Every one of them starts of spiritually dead. They are then made alive by the blood of Christ!

For if the blood of bulls and goats and the ashes of a heifer, sprinkling the unclean, sanctifies for the purifying of the flesh, how much more shall the blood of Christ, who through the eternal Spirit offered Himself without spot to God, cleanse your conscience from dead works to serve the living God? (Hebrews 9:13, 14)

Our sin had separated us from a holy God. We were without hope of curing ourselves, and were completely alienated from God. But the blood of Christ changed all of that!

But now in Christ Jesus you who once were far off have been brought near by the blood of Christ. (Ephesians 2:13 NKJV)

Even though we were enemies of God, Christ died for us in order to demonstrate His love for us. We have gone from being enemies of God to having peace with God! (Colossians 1:20)

There was a song written by Andrae Crouch many years ago ago the blood of Jesus, that said that the blood would never lose its power. Even though it was shed for us nearly 2000 years ago, it is just as potent as ever. It will save the worst sinner today the same way it would save one back then. The words of the chorus say, “it reaches to the highest mountain“. Even when we are on the mountaintop and have intimate communion with God, we still are only there because of the blood that was shed for us back at Calvary. Then it continues with “and it flows to the lowest valley“. No matter how far we have wandered in sin; no matter how far into the depths of wickedness our life has plunged, the blood of Jesus will still reach us right where we are if we will only appropriate it.

The words of John at the beginning of the Revelation some it up best:

and from Jesus Christ, the faithful witness, the firstborn from the dead, and the ruler over the kings of the earth. To Him who loved us and washed us from our sins in His own blood, and has made us kings and priests to His God and Father, to Him be glory and dominion forever and ever. Amen. (Revelation 1:5, 6 NKJV)

Smooth Talkers Need Not Apply
There are some smooth talkers that it seems could sell people anything. There are also some who can give a speech so moving that people run to join their cause. But when preaching, is that what God is looking for? Is He looking for the most gifted speakers or the most persuasive salesmen? Let’s see what the Apostle Paul said about his own preaching strategy.

And when I came to you, brethren, I did not come with superiority of speech or of wisdom, proclaiming to you the testimony of God. For I determined to know nothing among you except Jesus Christ, and Him crucified. I was with you in weakness and in fear and in much trembling, and my message and my preaching were not in persuasive words of wisdom, but in demonstration of the Spirit and of power, so that your faith would not rest on the wisdom of men, but on the power of God. (1 Corinthians 2:1-5 NASB)

Paul first says he did not come as a gifted speaker or philosopher. Paul was not an uneducated man, either. He was a scholar in his own right, and could have overwhelmed his audiences with the depth of his knowledge. But rather than give into the temptation to do so, he purposely avoided it. His message was simply about Jesus Christ and his crucifixion for our sins. He would rather be seen as weak and foolish than as a gifted orator.
Why? The focus had to be kept on Christ. How many sermon series being preached around the American church today are on things other than Jesus? Oh, He may get a cursory mention but Jesus is not the central focus of the teaching. The message is on how we can be happy, or prosperous, or successful. The message is a WIIFM statement (what’s in it for me) rather than centering our thoughts and actions on Jesus and what HE wants.

But what about the demonstration of the Spirit and power of God?

God also testifying with them, both by signs and wonders and by various miracles and by gifts of the Holy Spirit according to His own will. (Hebrews 2:4 NASB)

But know this first of all, that no prophecy of Scripture is a matter of one’s own interpretation, for no prophecy was ever made by an act of human will, but men moved by the Holy Spirit spoke from God. (2 Peter 1:20, 21 NASB)

While the signs and wonders of the Apostles were necessary for Showing that the message was from God, that message is now here for us. The power of the Spirit is demonstrated by the ability of the Bible to convict sinners and draw them to Jesus.

When we preach with the mission of drawing people to the person of Jesus Christ, and we use the Word of God to do so, the message has inherent power. That power will so draw people to Jesus that they will not be dissuaded by a worldly philosophy. A man with an experience is never at the mercy of a man with an argument. And their faith will be based on the Word of God, and not the preacher.

What is needed is a generation of preachers who are so in love with Jesus Christ that they can’t stop talking about him. Preachers who will draw their messages from the pure spring of living water found in the Bible, unadulterated by human philosophy and the wisdom of men. They will be men of power that can be mightily used of God to win their generation for Christ. The world can keep its smooth talkers and silver tongued orators. We want men to know nothing and long for nothing more, than the person of Jesus.
