Now when they heard this, they were cut to the heart, and said to Peter and the rest of the apostles, “Men and brethren, what shall we do?” (Acts 2:37).
The Book of Acts is an historical record of the spread of early Christianity throughout the Roman world. It’s a record of sermons and prayers, miracles and disappointments, angels and demons, arguments and love, murder and intrigue.
As Christians lived out their daily lives, God made opportunities for these believers to share their faith. Sometimes those opportunities were to hostile crowds, to a lone man headed home from a business trip, travelers in a shipwreck, or even to a judge during a court trial. None of these events were planned but came in the ordinary course of daily living.
In each of the instances of sharing the gospel of Jesus in the Book of Acts, not one person ever gave an “invitation” to be saved. No Christian ever asked, “Do you want to be saved?” In every case the person hearing the gospel asked what he needed to do to be saved. The Holy Spirit prompted the need to know within the unsaved person.
Churches are filled with un-saved converts. These are people who accept a man-made invitation apart from the work of the Holy Spirit. Man-centered evangelism forces the listener to make a decision and act in some way; in Biblical evangelism, the Spirit of God prompts the sinner to ask what he must do to be saved.
Be careful not to take over the Holy Spirit’s ministry and create false believers. If someone is to be saved, the Spirit will have already been at work revealing his sin to him and he’s just waiting for the gospel solution to be proclaimed.
