In order to understand God’s purposes in the earth, each generation must ask itself the same questions that were posed by threatening to the leaders of Judah when they returned to Jerusalem following the Babylonian exile: “Who in the world are you, and what on earth do you think you’re doing?” (Ezra 5:1−3). These questions penetrate to the very core of human existence, for they require conclusions first to identity and second to function—first, to being, second, to doing.
Far from being the solitary old man envisioned by most people, the God of the Bible is actually a community of three divine persons in one being of substance, Father, Son, and Holy Spirit. Being coequal, consubstantial, and coeternal, these three dwell together in a perfect community of oneness by means of their mutual encircling and interpenetration. Without the principles of the divine community, God simply does not exist.
