Some neighbors were having a party for the baby's baptism. We did not agree the theology of infant baptism, but we sent a card to show friendliness and be a witness. They had a pretty rowdy party that got pretty loud. At one point, someone said, "We should have baptism parties!"
We need to celebrate salvation so people will know how great it is. Let's have baptism parties! If we are full of the Holy Spirit, people should be coming to Christ. Acts 2:40-41
