I was just in a place where I asked the national leaders, "How do you do evangelism?" It was the first time in my 30 years of ministry that I had the response I received from them. They said, "Miracles." I asked them to explain. The explanation was that in their land of persecution and trial, it is hard to make "safe" contacts with people since there are so many unsafe people who can bring great damage to the church. They wait until people with illness or problems come to them. Then they pray. People are healed and miracles occur. Friends and family become Christians- they believe on the basis of what they see (John 14:11). Fear of recrimination is dissolved. The question, "Who is a safe person to talk to?" is not an issue, for the most part. When God demonstrates his powerful and loving presence, questions disappear as to suspicions.
That is New Testament. That is quite an evangelism methodology. It works for me.
