I think many people in the church are probably concerned that they can't answer all the questions that might come up. I am sure this affects people by playing on their doubts - especially if they have their own questions that they are wrestling with.

We can't know at any given time how God will bless our faithful witness. So the apparent numerical growth of the church is never a good guide to how faithful we have been in evangelism.

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.

God can use even stray, honest comments to bring people to himself.

If you think that the gospel is all about what we can do, that the practice of it is optional, and that conversion is simply something that anyone can choose at any time, then I'm concerned that you'll think of evangelism as nothing more than a sales job where the prospect is to be won over to sign on the dotted line by praying a prayer, followed by an assurance that he is the proud owner of salvation.

There are opportunities around. It takes time and motivation to take them.

Keep going until you get good counsel that is persuasive for you that you should go elsewhere.
