Ok I think I know where our difference is comming from. I think we have hearing and understanding mixed up. To me hearing is hearing. If I tell 100 people about Jesus and 1 understands it. To me all of them heard it but only the one understands it.
And I know I'm butting in here, and please excuse me for that, but if you think you speaking, or the person hearing are what save, your just wrong. Salvation is of God lest any man boast, yes you are to proclaim the gospel, and that person can only be saved by hearing that message, but it's the Spirit leading your words and the Spirit leading their understanding of what they hear. So while I think we'd all agree we are to obey, and we do proclaim His glory and point all to Jesus, but we'd never do this before being born again, we CAN'T do this before we are born again of His Spirit. I'm sorry, let me pull back a little, I can only speak for myself. I'd NEVER do any of these things if I was still of the flesh, or a slave to sin. It's Him, it's the Spirit that makes us all new, opens our eyes and ears to the things of the Spirit that we are blind to before we are saved by Him. It's not that we don't "do" anything, it's just He gets ALL the glory and credit for it. Praise Jesus awesome name.
