Paul also makes frequent references to Genesis 3. For example, he exhorts the Roman church to resist wicked deceivers, whose “smooth talk and flattery” (Rom. 16:18) is akin to that of Satan in the garden. Then he admonishes them “to be wise as to what is good and innocent as to what is evil” (v. 19), an obvious reference to the forbidden tree, for “the God of peace will soon crush Satan under your feet” (v. 20). By “soon” he has in mind the coming of Christ and the day of the Lord (cf. Rom. 2:5; 3:6; 4:17; 5:9; 6:5; 8:18–23; 10:9; 11:25–27; 13:12; 14:10–12), and the “God of peace” (16:20) is understood in light of the messianic passages wherein peace is proclaimed and established upon the earth under the Messiah’s rule (cf. Isa. 9:7; 66:12; Hag. 2:9; Zech. 9:10). - John P. Harrigan, the Gospel of Christ Crucified, p.126
