Truth is always exclusive. While it’s a big statement it’s been discussed already in a recent post here: https://thinkingbetweenthelines.wordpress.com/2012/12/11/exclusive-should-christians-claim-to-have-the-only-way/.
For now suffice it to say that all religions are making exclusive truth claims (saying that what they say is the only true option. Now, some are more willing to try to take in other beliefs, something like trying to bring a lion into your house because you thought it needed a home. But wild lions make poor pets and religious beliefs don’t live well within other faiths. For example, Hindus have historically tried to see Jesus Christ as an incarnation of Krishna. The omnivorous Unitarian Universalists would bring just about any truth claim into their circle. So when the lion comes to live in your house you must control it; when you take in another truth claim you must castrate it to make it safely fit.
We cannot have non-exclusive truth. Somebody is always wrong. And there is comfort in that: nobody wants to live in a land without borders. But if we cannot have non-exclusive truth would we prefer non-exclusive love? Perhaps.
Think of this: there are different types of love (the Greek language of the New Testament categorizes several – brotherly, romantic, unconditional, and familial). Of these only one is exclusive: romantic love. By its very nature it falls apart if it gets spread around. All the others can go from myself to any number of people and only grow by being given away to all and sundry. But if I tell someone I love romantically that I feel free to love any number of other people exactly the same do I truly love that person at all? How would you feel if the tables were turned on you?
Sometimes we are confused that Jesus expresses unconditional but not un-exclusive love. He loves just because that is His nature (I John 4:8). But love and truth are always wed and God can’t love everything. Would we want Him to? Would we want evil and good to be equal in His eyes? Would we want promises that we are told we can trust but that are not exclusive and can change at any time?
No, love chooses. It is the nature of love. Truth chooses. God chooses. We choose even if we choose to not choose. The beauty is that God chooses us (John 15:6). Truth and love require choice but they also require commitment and we don’t have a God who commits to move in with us but to marry us (in fact this analogy is used across the whole of Scripture). Because of this Love we need not merely shack up with the Truth.
