Let me talk to you for a little while this morning about something that’s not just good news—it’s the best news the world has ever heard: the gospel of Jesus Christ.

Now, most of the time when people think about the Great Commission, they turn to Matthew’s account. But today, I want us to focus on Mark 16:14–18, because there, Jesus makes something absolutely clear. He told the Eleven, “Go into all the world and preach the gospel to every creature.” That was His command. His desire. His urgency. Why? Because the gospel needs to be heard by everyone. That includes you.

But I want to ask you something: Have you truly heard the gospel of Christ? I mean, really heard it—all of it? Maybe you’ve heard pieces. Maybe you’ve even responded in some way in the past. But today, I want to take you back to the foundation—to what the gospel really is, what it calls you to do, and what it promises if you obey.

The Gospel Contains Facts to Believe

Let’s begin with the facts. This gospel is built on real, eternal, unchanging truths that must be believed.

The first fact is this: Christ was crucified for your sins.

Not just some people. Not just the “really bad” ones. Every one of us. Paul made that point clear in 1 Corinthians 15:1–3—when he said the gospel he preached was centered on Christ dying for our sins according to the Scriptures. This wasn’t a tragedy—it was a plan. A perfect Savior gave His life for sinners like you and me.

And why did He do it? Because all have sinned (Romans 3:23). That’s you. That’s me. And the wages of that sin? Spiritual death (Romans 6:23) refers to eternal separation from God. A darkness so deep, so terrifying, that it’s described as a place where “the worm never dies,” where there’s weeping, gnashing of teeth, fire, brimstone, and outer darkness—a place completely void of light, because Jesus, the light of the world, is not there.

But Jesus didn’t just die. He was raised from the dead—a fact just as important. Paul continues in 1 Corinthians 15:4, telling us that Jesus rose again on the third day, just as the Scriptures foretold. And Peter boldly declared the same truth on Pentecost in Acts 2:22–24: God raised Him up, because it was not possible for death to hold Him.

Another truth you must believe: Jesus is now exalted—King and Savior. Peter declared it in Acts 2:33–36. Jesus was lifted to the right hand of God. He reigns now. He is Lord and Christ. Paul confirmed it again in Ephesians 1:20–23—He is head over all things to the church.

And there’s one more truth you must not miss: Jesus is coming again. Acts 1:9–11 makes it clear—the same Jesus who ascended will return. And when He comes, He’s bringing rest to the obedient… and judgment to those who rejected His message (2 Thessalonians 1:7–9). That day is coming, and whether you’re ready or not, it’s real.

The Gospel Contains Commands to Obey

Now listen closely—because the gospel isn’t just something to believe. It’s something to obey. Jesus said in Mark 16:16, “He who believes and is baptized will be saved. He who does not believe will be condemned.”

That’s not a suggestion. That’s a command.

So ask yourself: Have you believed the gospel and obeyed it?

Paul said in Romans 1:16, “I am not ashamed of the gospel, for it is the power of God unto salvation for everyone who believes…”—but only to those who believe. Romans 10:9–10 says we must believe that Jesus rose from the dead and confess Him with our mouths.

And what else? Jesus said it plainly—you must be baptized. In Acts 2:38, Peter told the crowd, “Repent and be baptized for the remission of sins.” It’s not just a symbol—it’s the moment where God does His saving work, washing away your sins (Acts 22:16). You don’t earn salvation through baptism—you receive it by faith and obedience.

Let me say this clearly—infants cannot obey the gospel. They cannot hear, understand, believe, or repent. Baptism is for those who believe the gospel and want to respond to it with a new life.

You must also confess Jesus publicly (Romans 10:9–10; Matthew 10:32–33). You must repent—that means turn from your sin and turn toward Christ. It’s a change of heart and life. And once you’ve obeyed the gospel, you must remain faithful unto death (Revelation 2:10). Baptism is not the finish line—it’s the starting line. You must keep living for Christ, growing, serving, obeying every day.

The Gospel Offers Promises to Receive

Here’s the beauty of it all—when you obey the gospel, you receive promises beyond anything this world can give.

  • Salvation from sin (Mark 16:16, Acts 2:38, Acts 3:19, Acts 22:16).
  • Peace with God, and freedom from the wrath that’s coming (2 Thessalonians 1:7–10; Romans 2:4–11).
  • The gift of the Holy Spirit (Acts 2:38–39; Galatians 4:6).
  • Eternal life (Romans 6:22–23; John 10:10).
  • Abundant life—right now, in Christ.

Yes, you can have joy and purpose here on earth, and eternal rest and glory in the life to come.

So, Let Me Ask You…

What have you done with the gospel?

Jesus wants every creature to hear this message—and you’ve just heard it.

He said, “He who believes and is baptized will be saved. But he who does not believe will be condemned.” That’s not my word. That’s His.

Are you willing to believe the facts of the gospel?
Are you ready to obey the commands of the gospel?
Are you longing to receive the promises of the gospel?

This is your moment. Believe. Repent. Confess. Be baptized. Begin your walk with Christ. And if you’ve already started that walk but have fallen short, let’s go to God together in prayer. He’s ready to forgive.

This gospel is good news. It is power. It is life. And now you know what it asks of you.
