They have been spoon fed pabulum for so long that they have forgotten the essentials, so they have to tweak them to make them fit into their ignorance. They raise up their hands, walk down the aisle of the church and get saved, no sanctification, no repentance, no spirituality, baptized in water and not baptized in the spirit, just whitewashed and back into the world. This has been catastrophic to those that are earnestly seeking the truth. Once they get turned off by the carnal church, they start getting turned off by spiritual Christians and the love grows cold. This results in disunity, fragmented fellowship, alienation and a barrier to sound teaching.
Spiritual rebirth can happen all at once or it can happen in stages.
Every case scenario is different for every case. The worst teachers want to teach us the way that they have been taught but this is how false tradition gets started. Each person starts a new life in a new way and we are all unique. It has been said over and over that Jesus is either a liar, a lunatic or the Son of God. He is not just a prophet, He is not just a man, He is not just a God.
