This can be answered a number of ways. I think the way we need to view this rather is how is Satan using creation vs evolution to deceive the world.
Through my posting on this forum, it is apparent that many, if not all, YECs have a passion for the Word of God. YECs take the Bible's teachings over what man teaches.
I am not trying to say anything about TEs at this point. What I see Satan doing in this debate, if you will, is using each side against each other. What I mean is that many spend more time arguing about this then by spreading the Gospel message. Secondly, look at how we treat each other for all non-believers to see. We aren't showing God's love in our actions on this forum very often.
I am not pointing figures at anyone, but rather at everyone. We all are at fault for this, YECs and TEs.
After being here for a while, I have not seen one TE change his/her beliefs on origins. I don't believe I ever will on this forum. This forum is not conducive for hearing what another person says and taking to heart. It is more conducive to encouraging us to be stubborn and closed minded. Why? Because we must uphold our end of the arguement so we can win the debate.
At what cost are we willing to sacrifice for the win? Not spreading the Gospel as much? Participating in insults, sarcasm and anything else that is un-Christ-like?
When we do, we are playing into Satan's hand.
