Answer
When we talk about who God is and what Scripture reveals to us about who God is — what people call the attributes of God — people break them up into communicable, which mean things that are like us, or incommunicable, things that are very different between God and us. Or some people like to say immanent and transcendent: immanent more like us, transcendent that means beyond. So, those are the things that are true of God but certainly not true of us. Why is that distinction important? It's important because it helps us to understand who God is — God as distinct — and but also the ways that we come to understand God, that God has operated or does operate in ways that are like us when we think about love or mercy, those being communicable or immanent attributes. If we think about a word like "aseity," which means that God exists only by making himself exist. In other words, he depends on nothing; whereas, we are dependent on him for our existence — that's the kind of thing that tells us, okay, there's something very different about who God is from who we are. So, the incommunicable and communicable attributes distinction is good for helping us to know who God is, but also helping us to know how God is God and we are not.
