“Mystery is the lifeblood of theological reflection. From the start of its labors, dogmatic theology is shrouded in mystery. It stands before God the incomprehensible One.
This knowledge leads to adoration and worship: to know God is to live.
Knowing God is possible for us because God is personal, exalted above the earth and yet in fellowship with human beings on earth. Good theology puts this knowledge of God on public display.
It resists allowing theology to degenerate into rhetoric, a theology merely of words. It seeks the heart of the matter, knowing God in order to worship Him, to love Him, and to serve Him.
Such theology is never a dry and academic exercise. It is eminently practical and superlatively fruitful for life.
The knowledge of God in Christ, after all, is life itself (Psalm 89:16; Isaiah 11:9; Jeremiah 31:34; John 17:3).”
