Don't let the earth be the salt of the Church

Although the Church is supposed to be the salt of the Earth, sometimes the Earth becomes the salt of the Church. This is especially the case when Bible study isn't emphasised, and Church attendance becomes less about fellowship/edification and more just something that is done for the sake of doing it.

In our relativistic culture, the result is that modern Christians have become relativistic. So many people call Christians "narrow minded" for affirming... the Gospel.

Yes! Yes, Christianity is a narrow minded view. And so Christians should be narrow minded. Your liberal friend will dismiss you? Boo hoo. How do you expect to save their soul if instead of ushering them towards the narrow gate, you join them on the broad road to destruction? Narrow is the gate, and difficult the road that leads to life. If you want to be among the few who find it, stay on it, and encourage others onto it, too.
