He said he was a "fundamentalist" Christian.
From my perspective fundamentalists have an all or nothing approach. They don't cherry pick. That's good in one way, but does it cause pressure? Burn out? Especially when forced to defend the faith against atheists. They find they don't have convincing answers. They deep down question themselves.
So it would be interesting to survey those who quit Christianity. I know many Catholics quit believing due to sex scandals.
My hope is that if we imagine what it's like to be an atheist, that we come back gladly to believing in God again. That something doesn't feel right. God does exist, and I never want to imagine he doesn't, ever again.
I didn't watch the video, so I will just go by what yall have said of it.
The Christian faith is not so frivolous that one can just say, I don't believe anymore. Our faith comes from God. We believe because He has opened our eyes to Him and Christ. (Matt. 16:17) A believer can't quit believing because belief is from God.
A believer can become disobedient in his walk with God. Thereby exercising unbelief in obedience to what God has said. This is the unbelief spoken of in (Heb. 3:12). It is not the unbelief that the atheist demonstrates.
If I as a Christian am persecuted and let's say tortured into confessing that Christ is not real and God doesn't exist, do I become an atheist? No. I just become a lying Christian. God doesn't listen to my lie. He didn't listen to Peter's lie who denied Him.
If I try to shake God, and say I don't want this Christian faith anymore, guess what? You can't shake God. I simply become disobedient and miserable. He doesn't let go. But He will bring things into our lives to bring us back to Him, which may not be pleasant. I am thinking of (Jonah) at this time. Running from God. And even after he came back to God, he was still angry with God. (Jonah 4:1-3)
God puts up with a lot with His people. But He does not let them go.
