"Trinity understands God as three-personed: Father, Son, and Holy Spirit, God in community, each 'person' in active communion with the others. We are given an understanding of God that is most emphatically personal and interpersonal. God is nothing if not personal. If God is revealed as personal, the only way that God can be known is in personal response. We need to know this. It is the easiest thing in the world to use words as a kind of abstract truth or principle, to deal with the gospel as information. Trinity prevents us from doing this. We can never get away with depersonalizing the gospel or the truth to make it easier, simpler, more convenient. Knowing God through impersonal abstractions is ruled out, knowing God through programmatic projects is abandoned, knowing God in solitary isolation is forbidden. Trinity insists that God is not an idea or a force or a private experience but personal and known only in personal response and engagement."
