The difference between apologetics and evangelism is that in apologetics, you are answering objections that the world raises, whereas in evangelism, you are bringing the message that Christ brought. So unbelievers tend to set the agenda in apologetics, and you set the agenda in evangelism.

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.

God’s Word has always been His chosen instrument to create, convict, convert, and conform His people.

Evangelism is not simply looking at someone and saying, "Look, you have to become a Christian". Instead, an evangelist tells us the truth about who God is, and explains where we stand as a result of that. People can ignore us - indeed, they have every legal right to do so.

By the grace of God I am what I am

Let's say you don't want to stress the urgency of the gospel. Imagine that you are a hyper-Calvinist, and you just figure that people's salvation is a matter for the sovereignty of God. Well, if that's the case, there will never be the heartfelt pleading that you would see in a Spurgeon or an Edwards, or in the Apostle Paul where he pours out his heart in Romans 9 and 10 for the Jewish people.

I love people thinking about apologetics. I just think that we have to be careful. We need to realize that we can argue about evolution or the existence of God or any number of things, but until we tell people the message of the cross, we have not evangelized them.
