Anyway, my own experience with God is that you can be really close to him, then get angry with him and walk away.
MaxGrit tells me I was never (really) saved, so I guess everything I went through meant nothing.
Seems like he's trying really hard to save a doctrine that runs counter to many people's experiences during their faith journey.
You said "give up on God" which is a completely different matter. Many people get angry with God and become atheists, or, like Satan, hate God even though they believe He exists.
You should think before you speak. I was very insulted when you said I was "never saved." It seems to me you are being very presumptious to think you can make that judgment.
Who's is the judge? God is the Judge. No man can judge your soul.
Furthermore, I was agreeing with you when you said, "Yes, it is possible to be very close with God, and then lose hope and give up on God, and get angry with God." It's only possible because those people are in Category 2 (carnal faith, never saved).
You said "give up on God." Stop being insulted whenever people respond to your statement logically. It's illogical to say that God hating atheist ex-Christians were ever saved.
Think before you get insulted.
