my point was - people can go to any church and still God can reach them. Sure it doesn’t help that some churches are way off from biblical teaching, but God can use even those places to still reach people. If a person is willing God will help them hear what is Truth.
God also has solid followers at weak or off track churches. I know plenty who go due to spouse attends there and they go as a family. Those strong enough in their faith to attend (or called by God to be at) weak or off track churches without weakening themsleves are likely the light in the dark for others trying to grow or may be ministering to elderly etc who don’t have many options of churches to attend due to where they live and their ability to get around. They may be a pivotal person in many people’s lives in accepting Jesus or not.
The apostles even were called to live in and among back slidden church people. They themselves were off track at times and had many disagreements about what was right or not about following Jesus and His word and their Torah. Yet God did great things through all their doubts and pride and missteps etc.
Nothing’s changed since apostles/disciples times - it’s not about which church is right or better than another. The main focus should be each person and their heart/choice for Jesus and choosing to actually let Him lead their life, wherever that leads them.
Peter seems to have taken a somewhat harsher view of false teachers. 2 Peter 2. Paul in Galations, 1 & 5. Jude in its short entirety.
