What Do We Implicitly Know, and What Should We Instructively Know, about the Trinity?

The Bible is a story in which its Author is the chief character. We either know Him or we need to know Him. We learn the Trinity like children learning to speak: we use language and ideas before developing grammar and structure. Thesis: We know God as Triune in our devotion, and we need to learn how to speak of Him well. This material divides evenly between what we know already and what we should know.
