I'll tell you what's more important than all the commentaries in your library: prayer.

As long as quick numerical growth remains the primary indicator of church health, the truth will be compromised. Instead, churches must once again begin measuring success not in terms of numbers but in terms of fidelity to the Scriptures.

I love Iain Murray's definition of worldliness: towards the end of Evangelicalism Divided, he says that worldliness consists of loving idols and being at war with God. I think that's true in the lives of too many professing Christians today.

Christians, like everyone else, are prone to be selfish and scared, and wanting others to think well of them. So, although we possess what one part of us knows is the greatest news in the world, we don't act as though it is. Consequently, we share the gospel less than we should.

T]he church is not a place. It's not a building. It's not a preaching point. It's not a spiritual service provider. It's a people - the new covenant, blood-bought people of God. That's why Paul said, 'Christ loved the church and gave himself up for her' (Eph. 5:25). He didn't give himself up for a place, but for a people.

Sometimes we have to wait a long time to see conversions.

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.
