They think it strange that you do not plunge with them into the same flood of dissipation, and they heap abuse on you. 1 Peter 4:4
Peter wrote to Christians who had stopped doing things that were wrong like getting drunk and partying. He told them that the people that they used to party with will think it is strange that the person quit “having fun” with the rest of the crowd. In fact, some of their old friends would start making fun of them for trying to do right. Some would be jealous because they do not have the strength to quit doing wrong. Others just do not like to see people serving God.
Peter said that the crowd ran in a “flood of dissipation.” They were running in a crowd of wild living. So many people are doing it that it seems like a flood that threatens to destroy everything in its path. Jesus said that the wide path led to destruction but the narrow path led to everlasting life, Matthew 7:13. We need to travel the narrow path with Jesus though many of our old friends might make fun of us for doing so.
We and our old friends must stand before God one day. We want God to be pleased that we left the flood of wild living. He will punish all who will not repent of wickedness.
