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.

We mustn't be content to just sit around pointing out the errors in others; we actually need to be sharing the gospel and praying for people to be converted.

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.

We live in a time when people are increasingly skittish about evangelism - Christians and non-Christians alike. People are suspicious of evangelism, and misunderstand it, which contributes to our reluctance to share the gospel. When you add our fear of others' reactions as well as our natural laziness to the equation, it's not hard to see why we make such little progress in sharing our faith.

We should want to evangelize because of the joy that God puts in our hearts. Ultimately, that's the best reason for sharing our faith.

I don't mind talking about a football game - that's fine. I don't want Christians to be unnatural. But I do want to hear them talking fully, freely and naturally of the things of the Lord in their own lives too.
