Homosexual behavior, in particular, demonstrates the exchange of what is good and natural according to God’s created order for that which is evil and unnatural. Thus, it is an especially blatant form of idolatry, of telling the Creator that one will not have Him as Lord but will worship and serve the creature (Rom. 1:24–27). This sexual twisting, however, is not the primal sin of humanity; rather, it is the ethical outworking of the fundamental transgression, namely, the refusal to honor and thank God (vv. 18–23).
Furthermore, homosexual behavior is not the only way our fundamentally idolatrous dispositions show themselves. As we will see in tomorrow’s study, there are innumerable ways in which idolatry bears unethical fruit. Today’s passage, however, introduces the vice list Paul provides in Romans 1:29–31, reminding us once again of the root of all evil.
