Christian proclamation might make the gospel audible, but Christians living together in local congregations make the gospel visible (see John 13:34-35). The church is the gospel made visible.

Today is what the Lord has prepared you for.

We need the word proclaimed so that we hear the gospel clearly, but then it's also very natural to have people talk about the Christian faith in ordinary conversation.

A healthy church is not a church that's perfect and without sin. It has not figured everything out. Rather, it's a church that continually strives to take God's side in the battle against the ungodly desires and deceits of the world, our flesh, and the devil. It's a church that continually seeks to conform itself to God's Word.

Actually, having a few questions of your own shouldn't prevent you from sharing the gospel with others. You can explain to them that while you still have a few unresolved questions yourself, you don't have enough faith to not believe.

An evangelist no more imposes his views on others than a pilot imposes his views on his passengers when he lands a plane on a runway. I bet the passengers are glad!

If you need wisdom and guidance, then pray to the Lord to guide you.
