John records, Jesus said to him, “Go your son will live.” The man believed the word that Jesus spoke to him and went on his way. As he was going down, his servants met him and told him that his son was recovering. So he asked them the hour when he began to get better. (John 4:50-52)
If Jesus experienced the situation where people converted slowly rather than quickly, then so will we.
