Do you want to know that your new life is real? Commit yourself to a local group of saved sinners. Try to love them. Don’t just do it for three weeks. Don’t just do it for six months. Do it for years. And I think you’ll find out, and others will, too, whether or not you love God. The truth will show itself

Advice on evangelism needs to be tailored to individual situations. For instance, I know someone who needs to be encouraged to speak less and work more. That would be a better testimony for him because he has certainly let his work colleagues know about Jesus. It's not that I don't want him to witness about Jesus, but I have a lot of sympathy for his employer. He is paying for work to be done.

My task as a pastor is to remind people of the need for balance. If someone wants to stress personal union with Christ, I remind them of the need for knowledge as well. If they want to stress knowledge, I tell them about their need to depend on Christ.

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

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.
