What I take from it (from my Christian background) is simple, you could perform all types of works, miracles, good deeds (feeding the homeless and what have you) but if you did none of it out of love, it's worthless. You can have all the faith and hope in the world, but if you have no love, it's not worth anything. The word love is tough to talk about these days since so many people have their own definition of it, this love being the Biblical definition of love since it's in a Biblical context.

In fact, the context for 1 Corinthians 13 is the previous chapter: 1 Corinthians 12 where Paul writes about the church arguing over spiritual gifts, and he humbles them by saying something even simpler is more important than all of that, because they are arguing about the wrong things, basically who does the most works or miracles, but it's all worthless if you can't even love one another. Anytime I try to make an opinion about a Bible verse or chapter I go back and read the previous verse or chapter for context, it clarifies things a lot.

I'm not disagreeing with you btw, the point still remains, you can have really strong views on something, but they may not matter, you may find out (from a Christian viewpoint) in the end that they were partially right, or fully wrong and all the arguments were a waste of your life when you had better things to do.

I used to really get into theological arguments on Facebook Christian / Bible groups, but it's kind of a waste of time, most people reading what I have to say likely already made up their minds.
