One of the great problems we have in discussing the Trinity is that there is so much miscommunication. Our goal then is to explain the Trinity in simple terms. We do this very well with little ones. When we introduce them to something they have never tasted, we often give them an idea of what it tastes like. For instance, we say that this new food tastes like crackers and honey. Now, they are able to associate the new food with something they have tasted before. When it comes to the doctrine of the Trinity, we are in dangerous grounds every time we begin the sentence “God is like…” The problem is we are not speaking of things we have seen, tasted, or experienced. God is a Spirit, says John. What is a spirit? Have we ever seen a spirit? What can we compare it to? Language does not permit us to define neatly the indefinable. God is completely unique and to “compare God to anything in the created order is, in the final analysis, to define His uniqueness.”
 James White, The Forgotten Trinity, 25.
