Have you ever met someone who claims they are a Christian yet their life shows no evidence? The only thing that points to the Christianity is their bare claim. People who, “claim to know God, but by their actions they deny him” (Titus 1:16)?

In no uncertain terms, the Bible exposes this and calls it what it is: false conversion. Those whose lives are unaffected by the gospel of Jesus Christ prove that they do not know Jesus Christ. They may claim to know Him, but, as John says, they are liars and the truth is not in them (1 John 2:4).

How can I say this? Because Jesus does:

Beware of false prophets, who come to you in sheep’s clothing but inwardly are ravenous wolves. You will recognize them by their fruits. Are grapes gathered from thorn bushes, or figs from thistles? So, every healthy tree bears good fruit, but the diseased tree bears bad fruit. A healthy tree cannot bear bad fruit, nor can a diseased tree bear good fruit. Every tree that does not bear good fruit is cut down and thrown into the fire. Thus you will recognize them by their fruits. (Matthew 7:15-20)

The truth is, the salvation that Jesus offers is not just something done for you, it is something done to you. Being saved by Jesus Christ means being made into an entirely new creation (2 Corinthians 5:17) and being made a new creation will make an observable difference in everything you say, think, desire and do. If you become a Christian, it will show. In illustrating this truth, Paul Washer brings it home.

Let’s imagine that I show up late and I run up here on the platform, and all the leaders are angry with me and say, “Brother Paul, don’t you appreciate the fact you’re given an opportunity to speak here and you come late?”

And I’d say, “Brothers, you have to forgive me.”

“Well, why?”

“Well, I was out here on the highway, and I was driving and I had a flat tire and I got out to change the tire, and when I was changing the tire, the lug nut fell off, and I wasn’t paying attention that I was on the highway and I ran out and I grabbed the lug nut, and as soon as I picked it up in the middle of the highway, I stood up and there was a 30-ton logging truck going 120 miles an hour about ten yards in front of me, and it ran me over and that’s why I’m late.”

Now, there would only be two logical conclusions. One, I’m a liar or, two, I’m a madman. You would say, “Brother Paul, it’s absolutely absurd. It is impossible, Brother Paul, to have an encounter with something as large as a logging truck and not be changed.” And then my question would be to you–What is larger? A logging truck or God?

How is it that so many people today profess to have had an encounter with Jesus Christ, and, yet, they are not permanently changed? Let me give you a few things to think about. How many times do you go and rededicate your life over and over and over again? How many times do youth groups go to things like this and get fired up and go back to the church, and it lasts about a week and a half? And yet, “Oh, it was a great move of God.” No, it wasn’t. If it doesn’t last, it wasn’t a great move of God. It was emotion. It was so many things, but it wasn’t a great move of God.

You will know them by their fruit.

You will know them by their fruit. (Taken from this sermon)

To sum it up, Jesus is bigger than a semi-truck. Meeting Him will change you and others will notice. A Christianity that doesn’t change you is a Christianity with no Christ. If you haven’t been changed by Jesus then you haven’t been saved by Jesus, but take heart, His offer still stands today. Read of it here.
