Debate is a good thing.
Arguing is not.
Most do not understand the difference.
In debate both people should be able to pose their beliefs in a calm, rational way. Not only should they be able to state what they believe, but why they believe it.
In arguement, I am right, you are wrong and I dont need to support my position or beliefs because with my hard heart I'm not listening to you anyway, my pride and ego wont let me.
Debate you can, at the very worst come to a respectful stalemate where you or they walk away with at least some understanding of your or their beliefs and why.
If you debate and your beliefs and whys do not contradict themselves.. you cant lose when you know what you believe and why.
Arguing is nothing more than a waste of time.
There is not a doubt in my mind that Christ would debate while He walked the Earth, because debate is about discussing ideas, it's nothing more than a respectful conversation on one topic... with a goal. (The goal being to put truth out there, and let it be heard. In a manner that doesnt need to state "I'm right you're wrong" as truth, is truth and truth calls out to those that truly desire truth and light.)
Arguing being a waste of time, I do not see Jesus doing because it doesnt matter how many truths are spoken... if they do not have ears willing to hear those truths.. it will change nothing, do nothing but waste time.
