They have to accept Jesus usually first (with notable exceptions, like Saul of Tarsus) before the Holy Spirit comes upon them and their hearts become circumcized.
BTW;
The exact word "evangelism" does not appear in the Bible as-is. The term evangelism describes teaching the Christian faith which was first used in more recent times circa 1626. The word "evangelist", however, appears at least 3 times depending on the translation.
From the Greek word euaggelizo we get "evangelist", which means a preacher of the gospel. This name was given in the New Testament to those heralds of salvation through Christ who were not apostles. However, the Greek word in its various forms appears fifty-five times in the New Testament with the more general context of peaching the gospel or preachers of the good news, etc.
