Worldliness in the church is a lot more pervasive than a lack of passion for evangelism. Nevertheless, one of the results of worldliness is a waning enthusiasm for evangelism.

I don't see a clerical class in the New Testament to which evangelism has been delegated. Preaching is not the only way to evangelize; it can happen in everyday conversations too. And you don't need a special gift to witness to the Lord in these situations.

Evangelism is not imposing anything on anyone; it is simply sharing the truth.

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

I guess I tend to see divine appointments everywhere. I am always on the alert for opportunities. So I prefer to err on the side of witnessing too often than not enough.

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.

I heard about a pastor in a church of 5,000 people who employed two seminary students whose main responsibility was to get four new people baptized each week. When asked, "What happens if they can't meet the quota?", his response was, "Then I'll find two students who can". This man wasn't even remotely interested in true gospel preaching. He was results-driven.
