The Scripture's image for God's authoritative self-revelation, both audible-historical (at Sinai, baptism, transfiguration) and ongoing (through Scripture and the Spirit's application). Psalm 29 is the canonical voice-of-God psalm: The voice of the LORD is upon the waters: the God of glory thundereth... The voice of the LORD is powerful; the voice of the LORD is full of majesty (vv. 3-4). The voice splits cedars, shakes the wilderness, makes hinds calve. Scripture's great audible-voice moments: God walking and calling in Eden (Gen 3:8-9); Mount Sinai (Ex 20); Elijah's still small voice after the storm (1 Kgs 19:12); the voice at Christ's baptism (Matt 3:17) and transfiguration (Matt 17:5: This is my beloved Son, in whom I am well pleased; hear ye him). God's primary ongoing voice today is His written Word: God, who at sundry times and in divers manners spake in time past unto the fathers by the prophets, Hath in these last days spoken unto us by his Son (Heb 1:1-2). The Son has spoken; Scripture preserves what He said.
