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.

Testimonies are great things about what the Lord has done for us, but no-one will be offended when you talk about what God has done for you. You need to be specific about sin, about Christ's death on the cross, about others' need for a saviour, and about their need to repent and trust in Christ.

The important thing when you are tied down is to continue to model Christ's love. This will ensure that your words, perhaps spoken long ago, will have fresh relevance, or it will help little ones to understand what it means to live the Christian life in days to come. A life well-lived in these circumstances can be hugely useful in evangelism.

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.

The gospel of Christ has never needed the gimmicks of man to effect conversion in the soul

If you have no interest in actually committing yourself to an actual group of gospel-believing, Bible-teaching Christians, you might question whether you belong to the body of Christ at all!

Evangelists have absolutely no desire to physically or emotionally coerce anyone. In a sense, we are like doctors: we have a duty to tell you the truth, care for you, argue with you (if that is useful), but we can't compel you to do anything.
