When we are baptized with water (as John the Baptist did) by immersion, man dies and renounces what he was before, and when he emerges from the water he is resurrected together with Jesus, now you refer to Christians who are looking for material things that are from one church in another looking for where to be comfortable, I call them "Swallows" who are from one place to another looking for where to feel better and do not put their eyes on Jesus Christ the author and finisher of all things, good reflection .
