After Paul addressed a crowd in Athens, his listeners responded in three ways. Which do you think was the very worst?

When they heard Paul speak about the resurrection of the dead, some laughed in contempt, but others said, “We want to hear more about this later.” 33  That ended Paul’s discussion with them, 34  but some joined him and became believers. Among them were Dionysius, a member of the council, a woman named Damaris, and others with them. Acts 17:32-34 (NLT) 

Lack of interest is the worst response to the gospel. Far better that a person be hostile than be indifferent.

Jesus warned in Revelation:

I know all the things you do, that you are neither hot nor cold. I wish that you were one or the other! 16  But since you are like lukewarm water, neither hot nor cold, I will spit you out of my mouth! Revelation 3:15-16 (NLT) 

Even though Jesus spoke these words to the church, the principle still applies. If people actively resist the gospel, it is because they are seriously listening and do not like what they hear. There is hope for such a person. Perhaps the Holy Spirit will bring them around as they continue to ponder the implications of the gospel. The “lukewarm” disinterested person, however, will probably not give the gospel a second thought. He does not think he is rejecting the message, just saving it for later consideration, which quite probably will never happen. Procrastination is not a virtue when it comes to the gospel. The “hot” response is most to be desired. These people “get it” and respond positively right away.  The next time someone becomes hostile to the message, we should give thanks to God. At least we were heard.
