A new believer needs to be welcomed into the body and this is not always easy. Saul, the murderer, was viewed with suspician until Barnabas took the steps necessary to win over his acceptance by the church in Jerusalem. And it was Barnabas who recognized the potential in Paul as a Pastor and Missionary and defender of the faith. Now this same person has started coming to Sunday School. Be sure and highlight in some way each of the points in the outline above.
Many fears are unrealistic.
Present the need to go and share Christ with everyone, even to those are hostile to Christ. It is for sinners that Christ came and died. Present the need to accept and welcome into the church those who have come to know Christ even though they were formerly undesirable or feared. If any man is in Christ, he is a new creature. We are reluctant to take the time and give of ourselves as friends to newer believers.
