How is it that someone could appear to be radically converted and so passionate about their new faith and then, without warning, suddenly give up and walk away?
I have met people who were emotional about Jesus and fired up about their faith, only to later fall into gross sin. What happened? I think they really never were rooted in Christ. Some people are just impulsive by nature. They are always into the latest fad. Whatever gets their attention, that is what they want to be into.
Case in point: exercise equipment. Just walk though a neighborhood on a Saturday afternoon when people have their garage doors open. See all of those exercise machines? How many times have you actually seen someone working out on one of them? Instead, there are usually things hanging on them. Someone decided they were going to get into shape, but their enthusiasm didn't stand the test of time.
That is what happens with some people who make a commitment to Christ. They may be excited in the beginning, but it doesn't stand the test of time. One possible explanation is they put their faith on the wrong foundation.
Maybe they decided to follow Christ because their friends did. Or maybe they put their faith in a certain church, and they found out that it wasn't perfect, that it was filled with flawed people like them. Perhaps some pastor didn't measure up to their expectations. Whatever the problem was, they didn't build their foundation on Christ. The Bible tells us, "For no one can lay any foundation other than the one we already have—Jesus Christ" (1 Corinthians 3:11).
This is the only foundation that will sustain us as Christians—not a person, not a preacher, not a church, but Jesus Christ.
