In chapter four, DeYoung explains Paul’s argument in Romans 1, and shows how same-sex activity is an affront to God’s design. Paul's description of humanity's downward spiral into sin includes three “exchanges”: 1) Ungodly men exchange the glory of God for the foolishness of idolatry; 2) ungodly men exchange the truth about God for a lie; and 3) they exchange natural relations with members of the opposite sex for relations with those of the same sex.
DeYoung answers the arguments of “revisionists” who try
to explain away the Scripture’s opposition to same-sex relations. Romans
chapter one is about homosexual activity in general, and not just (as
revisionists claim) sexual abuse of adults with youth or masters with slaves.
Some quotes:
Homosexual behavior is a sin, not according to who practices
it or by what motivation they seek it, but because that act itself, as a
truth-suppressing exchange, is contrary to God’s good design. (p. 53)
According to Paul’s logic, men and women who engage in
same-sex sexual behavior – even if they are being true to their own feelings
and desires – have suppressed God’s truth in unrighteousness. They have exchanged the
fittedness of male-female relations for those that are contrary to nature. (p.
55)
