Water is usually a good thing, except when it sits there for long time. When it does that, it harbours germs and other nasty things. You couldn’t drink that water, or use it in any way, shape, or form. It’s good to use it when you actually can use it, germ free, healthy, and beneficial. we as Christians can be the same way. We can either be water that sits there and rots, or we can be water that is healthy, and beneficial to anybody we come into contact with.
