And... in this corner...
Ha! You thought I was going to say Atheists. Or one of the many different religions floating around our world. That would have made more sense, perhaps. And yet, quite honestly, most of the debates/arguments/blood baths I've witnessed have not been between Christians and other groups. It's been Christians against Christians.
A Christian arguing with any other group has a very easy argument - The Bible tells us God is the one true God, and that His Son, Jesus Christ, died to save us. And the person on the other side of the debate doesn't believe in that God or the Bible. Easy.
A Christian arguing with another Christian, on the other hand...
Not only are these arguments even more difficult to participate in... I mean, you have to actually research the Bible and dig into your memories of what you've been taught and pray on what the truth is... these arguments also get very mean. And oh my God, do you know how annoying it is to hear Bible verses about false prophets during these fights? Seriously - there is always one person (at least) accusing the other of being a false prophet... or of following false prophets.
But the truth is - not all Christians are going to agree all the time. What is important is we agree that God created everything; and He sent Jesus to die for our sins. Anything above and beyond that, while important, should not be important enough to divide us. As long as we continue battling with each other, we will never be able to bring non-believers to God.
We are supposed to love one another, including our enemies. This is a commandment given to us by Jesus. This is a commandment we must follow if we are to have any hope of spreading the news of Christ.
Fighting, arguing, refusing to listen - this is not a way to spur others on to love and good deeds. When we get in that ring, and realize we're up against a fellow Christian... forfeit. You've both already won... why carry on the fight?
