Our thinking of God should begin with His name(s) as found in the Bible. Theology itself should begin here too. In his massive book, THE DOCTRINE OF GOD, Dr. John Frame writes on “Biblical Descriptions of God” beginning with a simple — yet profound — chapter on the ‘names’ of God. It’s a great chapter to study, and a model of doing clear, biblical thinking about God.
God’s name is his self-revelation. NAME, in the general sense, is a virtual synonym of word. And, like word, it is a way of referring to God himself. There is an identity between God and his name, as between God and his word. As we sing praise to God, we sing praise to his name (e.g., Pss. 7:17; 9:2; 18:49); we give to him the glory due his name (29:2); we exalt his name (34:3) and fear it (61:5). God’s name is an object of worship. Since in Scripture God alone is the proper object of worship, this language equates the Lord’s name and the Lord himself.
Similarly, the name of God defends us (Ps. 20:1) and saves us (54:1). We trust in him name for deliverance (33:21). His name endures forever (72:17; 135:13). It “reaches to the ends of the earth” (48:10). It is holy and awesome (111:9). god guides us “for his name sake” (23:3). In Isaiah 30:27, it is “the Name of the Lord” itself that comes to bring judgment on the nations and blessings on his people. So God’s name has divine attributes and performs divine acts. In short, Scripture says about the name of God virtually everything it says about God.
