The obedience of Christ
Robert Reymond writes:
The NT speaks explicitly of the obedience of Christ only three times: “through the obedience of the one man the many will be made righteous” (Rom. 5:19); “he humbled himself and became obedient to death” (Phil. 2:8); and “he learned obedience from what he suffered” (Heb. 5:8). But the concept these verses contain is clearly alluded to in many other places, e.g.,
(1) the several contexts in which Christ is called “servant” (Isa. 42:1; 52:13; 53:11; cf. Matt. 20:28; Mark 10:45);
(2) the numerous passages where he declares that his purpose in coming to earth is to do his Father’s will (Ps. 40:7–8; John 5:30; 8:28–29; 10:18; 12:49; 14:31; Heb. 10:7);
(3) the oft-made assertion by himself and both friends and enemies alike of his sinless and righteous life (Matt. 27:4, 19–23; Mark 12:14; Luke 23:4, 14–15; John 8:46; 18:38; 19:4–6; 2 Cor. 5:21; Heb. 4:15; 7:26); and
(4) the passages that affirm his submission to authority (Matt. 3:15; Luke 2:51–52; 4:16).
