Col 3:14 (NIV) "And over all these virtues put on love, which binds them all together in perfect unity." (TM)
Binds is the key word here. Holding together. Taking disparate items and joining them together into a useful compound. Unity.
Love is kind of like the milk in a batch of pancake batter. You mix the milk in thoroughly, but you don't stir forever. Your batter can handle small lumps of dry flour in there, because the milk will soak in during the cooking process and moisten it. But if the lumps are too big, then you'll have big, gross, icky lumps of dry flour in your mouth when you're eating.
So what's the point? Love needs to permeate every level, every part of your project, your community, your life, your whatever. You don't need to force it or be a nazi about it, because love just needs to be in close proximity to do its thing. It will have its influence on everything nearby.
