Well, I appreciate your faith in God - seriously!
But....does that mean that effort towards conversion and understanding comes to a stand still?...doesn't, 'the Spirit will guide whoever seeks the truth', make everything right?
Seems to me that we are called to relate God's love towards each other, despite the pristine condition of the law......
Lol. I've already stated, that in explaining the Scripture, they could say, This is equivalent to you coughing before you enter your friend's house." I have no issues with that. I definitely wouldn't want to take the risk of changing the Holy Scripture. Also, if you keep reading in that verse, it states that Jesus will come and sup with us. I think that even if they couldn't quite get the knocking from an explanation, if they thought about it, a robber WOULDN'T be supping with you. Therefore when Jesus comes knocking, he's not a robber. Even the most primitive man on earth has a God-given brain that allows him to take 2+2 and make 4 :)
I'm not saying we shouldn't try, but I have watched people deep in heresy unable to get out, because they didn't really want the truth. They refused to open their eyes to see the errors in their doctrine. If someone really desires the truth, the Spirit of God will lead them. Cornelius is an excellent example. :)
