I am not even sure you know what you are saying. A follower of Christ, someone who is genuinely saved, is not going to be a "non follower". Something may happen along their path that leads them to give up what they are doing, but the Holy Spirit will eventually guide them back. In my experience what usually happens is that some ultra IFBer (pastor, evangelist or even a layperson) will be so discouraging that the follower comes to a point where they don't see how they could possibly live up, perhaps even doubting they were ever really saved in the first place, and just give up. Woe be it to those Pharisees that do this. A friend of mine was part of a growing work in Florida, let's call it Anathema Baptist Church, that took an abrupt change after the pastor fell under the influence of a prominent IFB leader. Wanting to serve God no longer mattered, serving the pastor and submitting to him became everything. The pastor demanded that all church servants attend Thursday night soulwinning. No other night or day was acceptable to the pastor. If you did not go out with the Church on Thursday, then you would have to vacate whatever service you were performing on Sunday; SS teacher, choir member, usher, nursery worker, greeter, etc. There was no valid excuse for not going out with the church. Every service the pastor would question the ushers as to how many people each of them had won to Christ that week. On Wednesday night, the pastor would have all those going out soul winning on Thursday to stand and then spend the next 10 to 15 minutes berating those not standing, questioning their Christianity, if they loved God or if they were even really saved. From my understanding many left the church and the things of Christ during this. They might not be "following God" these days, but they are still His.
