When a person becomes a Christian, he doesn’t just join a local church because it’s a good habit for growing in spiritual maturity. He joins a local church because it’s the expression of what Christ has made him—a member of the body of Christ.

We are all called to have faith. So all of us are called to evangelize, while some are specially gifted for this ministry.

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.

To evangelize properly by delivering the gospel, we need to follow God's agenda.

It's fine to deal with people's doubts and explain why they have good reasons to believe in Christ. But until we tell them the good news of Jesus Christ, we haven't done our job. They need a saviour that God has provided them in Christ. Once they know that, we can do as much apologetics as we need to.

The more you come to know the Bible - both in reading it extensively and also meditating on it deeply - the more integrated your understanding of all of life will be. And this means that there will be fewer steps between what you are doing at work and sharing your faith in Christ.

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.
