I think crsschk has hit the nail on the head with this one.
There will never be a time when you will agree with absolutely everything that someone else says to you, and I think that that is a good thing. Disagreement and discussion, in the right spirit (!), are good and healthy, because they cause you to think about what you believe, and bring into question some of your own thoughts and ideas. Many a time I have jumped in on someone all too quickly with my own thoughts, which I thought were right and Biblically sound, only to get blown away because I have never actually [i]thought[/i] about what I think, and why I think it. Many things I have thought right were not, and I would not be corrected in those thoughts if someone had not offered a new perspective on things.
If someone has a new idea or thought about the Bible, and even if it seems wrong to you at the outset, it is useful to think about. It may shed light on your perspective, and show it to be good and Biblical, or it may well do the opposite and challenge you to consider what you believe because it is not as Biblically solid as you originally thought it was.
For an example, my uncle was taught at a certain Bible college, that when the Israelites crossed the Red Sea, God didn't part it. Apparently, the Red Sea was at a certain time of the year, so that the waters were shallow enough for the Israelites to walk through the sea on the reeds underneath them (!). Of course, I immediately jumped back and cried, 'Heresy! The waters were parted!'. I straight away thought to myself, 'These guys are wrong' (which I do believe they are!), but of course, it caused me to pick up my Bible and read for myself.
And, as I found in Exodus 14:21-22 (NIV),
'Then Moses stretched out his hand over the sea, and all that night the Lord drove the sea back with a strong east wind and turned it into dry land. [b]The waters were divided[/b], and the Israelites went through the sea on dry ground, with [b]a wall of water on their right and on their left[/b].'
Now, if I had done my usual thing and rashly thrown in my opinion without considering what these men had said, and picked up my Bible to read for myself, I would have had no grounds for my accusation of un-Biblicall-ness. But I did read God's Word, and as it said there in black and white, the waters were, of course, parted into two walls.
So my painfully long-winded response would be this - don't be alarmed by new ideas. Embrace them, think about them. Even if they seem wrong, go straight to God's Word and see what He would say on the matter. New views and ideas that do not match up with yours can do one of two things,
1) Challenge you to reconsider what you think by shedding light on the fact that you may not actually be correct, or
2) Solidifying your current thoughts even more, because you thought about them and found them to be Biblically correct.
In my case, I thought about what these guys said, read what God said and saw if they matched up with eachother. They didn't, and so in future if this theory of the Red Sea came up, I could then blow them out of the water (no pun intended) with God's Word. God is a miracle worker and He is all-powerful. He [b]did[/b] part that sea, my Bible tells me so, and now I can gaze in awe at this awesome God that I serve, who can actually part a sea into two! Incredible.
Sorry, what was the question again? Hope this helps!
