For we also have had the gospel preached to us, just as they did; but the message they heard was of no value to them, because those who heard did not combine it with faith.
Sometimes the most frustrating part about evangelism is the fact that even if we get someone to listen, we still have no control over whether they accept the message or not. In the end, we are only responsible for ourselves and we can’t make choices for our family, friends, or coworkers.
Hearing the gospel is only a part of evangelism. Unless faith is applied to the message and a person believes, the proper knowledge does no good.
A professor at Harvard once taught on the book of Romans, explaining the gospel beautifully and in the context that Paul wrote it. At the end of the class, a student raised their hand and asked “You don’t really expect us to believe this, do you?”
The professor responded, “No, I’m just telling you the way people understand this book.” All of this knowledge did no good because it was not combined with the faith to believe it.
It is our duty to get the gospel out. We can’t make someone believe it however. In the end, they must make that decision on their own.
