By far the greatest danger in apologetics is being distracted from the main message. Evangelism is not defending the virgin birth or defending the historicity of the resurrection. Apologetics is defending the faith, answering the questions others have about Christianity. It is responding to the agenda that others set. Evangelism, however, is following Christ’s agenda, the news about him. Evangelism is the positive act of telling the good news about Jesus Christ and the way of salvation through him.
Apologetics is a good thing, but it isn’t the power of God:
For I am not ashamed of the gospel, for it is the power of God for salvation to everyone who believes, to the Jew first and also to the Greek. (Romans 1:16 ESV)
