While he's in Athens Paul shows us how it's done.
In particular, Paul provides us with an excellent example of how to speak to unbelievers about Jesus Christ. Please click here to read the passage and then return.
This is master evangelism.
First, Paul makes a connection with those listening (17:22-23).
Second, Paul describes who God is and what He has done (17:24-29).
Third, Paul calls for repentance (17:30).
Fourth, Paul tells of Jesus Christ and His resurrection (17:31).
Paul understands that he must start at the beginning; he is not dealing with listeners who understand the Old Testament (as they would, for example, in a synagogue). The apostle proceeds to inform the men of Athens about the glorious nature of the God of the bible. Without using harsh words, Paul shows that God is far greater than anything the people of Greece had conceived. Simply put, God as revealed in Jesus Christ is superior. In light of what Christ has done, everyone has the responsibility to repent. Paul, as always, mentions the resurrection (this is critical).
Take note that Paul did not make this overly complicated. He also didn't need to speak for thirty minutes to explain the basics. He just started where his listeners were and went from there. As is usual, some of the people mocked, some believed, and some wanted to hear more.
Sometimes we make sharing Christ into a burden by thinking of it as much more complex than it is. If we will follow Paul's model we can avoid this. We make a connection, tell how great and wonderful God is, tell what He has done in Christ, and make a call for repentance and faith. This is not a rote formula to be memorized. Rather, it is simply a helpful guide to us. Let's use it.
