It happens more often than not that I go to a normal church and feel totally out of place. Like I belong to a completely different religion. (I probably shouldn't be saying this, taken that I'm an official missionary sent out by a trad church.) It is mainly stuff like sin and heaven that makes me wonder if I belong to the same thing. Trivial things like that. Or I think to myself, "Wait, does the Bible actually say that?"
Hear this. Now this is eternal life. Oh, wait, what does Jesus actually say? THIS is eternal life: that they might know you, the only true God, and Jesus Christ, whom you have sent. (John 17:3)
Not a word about streets of gold, worshipping God all day long, sitting on a cloud or even a place we go to when we die. Eternal life according to Jesus is to know himself.
I guess Paul would have it as knowing that in him we live, move and have our being. (Acts 17:24-28)
Makes me once more wonder where the notion that salvation is about heaven and hell came from. Or that heaven is most and foremost a place. I don't know.
