Brotherly Wisdom

"I've often reflected on the rather obvious thought that when his disciples were about to have the world collapse in on them, our Lord spent so much time in the Upper Room speaking to them about the mystery of the Trinity. If anything could underline the necessity of Trinitarianism for practical Christianity, that must surely be it!"
-Sinclair Ferguson, in a person email to Robert Letham (cited in The Holy Trinity, p. 375)

Two things scare us away from considering the Trinity as a practical truth of the Bible:
1. Its status as a "mystery." We think a doctrine's being mysterious excludes it from our contemplation and adoration. (Note how many prayers of our could easily be prayed by Jesus Only Pentacostals, and how many of our hymns and praise songs could be sung to a unitarian god) Add to this the fact that the cross is a mystery, and we must conclude that a. we've overestimated our ability to comprehend the cross or b. mysteries can be and, in fact, do belong at the heart of a vibrant faith in an ineffable God.
2. A cultural separation between academic and devotional knowledge. (Historians, I know, our culture didn't create this, Scholasticism and then the Enlightenment did, but it thrives in our atheological climate.) Somewhere, someone started the ridiculous notion that there are some truths of the Bible that belong exclusively to seminary professors and academics. Nevermind the fact that they will nurture your faith, enrich your prayers, and vivify your affections for a God who so loved the world that He gave His Son so believers in Him could have His Spirit, the Giver of Life...you can't have those truths, they belong in the academy, and if they escape and creep their way into sermons, devotional materials, or favorite evangelistic Bible verses, those materials will become stale and cold.
I suggest an alternative. Worship, pray to, and know the God of the Bible. The God(the Father) in whose Light(the Spirit) we see Light(the Son). Ps. 36:9
