This Person, to be sure, is a speaking person, and His Word is infallibly authoritative. He is, not because it exists in an abstraction. The Triune God gives them a revelation suited to their creaturehood. His children are called to love and obey their Creator, submit to His revelation, and work out its implication in every area of life. They do this well when, abandoning all autonomy, they humbly submit themselves to God, a Person.
Godly men produce godly theology.
Therefore, the first requisite of the theologian is a regenerated life in total submission to God and His Word. If God is a Person, and created man in His image as a Person, their relation can scarcely be anything other than personal. This is a false dichotomy. When my wife writes me a letter, my relationship with her is conveyed and enhanced by propositions. Yet the relationship itself is not propositional, but personal.
