And that's a command in the Bible because the Bible says darkness and Light have nothing in common, but I would say that anyone that leaves the faith were never of The True Faith meaning they were never truly Born of God Born again Born from above Born of Incorruptible seed, Regenerated. I was an atheist for 31 years and I was gloriously saved in 1994 through the conviction of sin John 16: 8-9 after my wonderful beautiful mother had prayed for me for 16 long years. And now I will be with her once it is my time to go Home to be with Jesus and to be with her and my father and my siblings who are all in Heaven now, thank you Jesus
