Michael Horton, CT: [S]in is not just a behavior. Long before they made any choice about what to do with it, people were predisposed toward same-sex attractions. . . . We reject the Pelagian reduction of sin to an action that one can overcome with enough will-power. We are depraved (warped) in every respect: spiritually, morally, intellectually, volitionally, and physically. . . .[W]e can inherit specific sins—or at least tendencies—of our fathers and mothers. Then add to that the ways in which people are sinned against by the attitudes and behaviors of others, especially in childhood. So even before we actually decide to take that first drink, place that first bet, unleash our first punch, or fool around with our best friend, we are already caught up in the tangled web of solidarity in sin. At the same time, we are responsible for our choices, which reinforce or counter the specific sins toward which we are especially disposed.
There is no reason to think that Christians who struggle with these attractions are any less justified and renewed by God's grace in Christ than are those who wrestle especially with greed or anger or gossip. The gospel frees us to confess our sins without fear of condemnation. Looking to Christ alone for our justification and holiness, we can finally declare war on our indwelling sin because we have peace with God.
If there is no biblical basis for greater condemnation, there is also no scriptural basis for greater laxity in God's judgment of this sin. It is as unloving to hold out hope to those who embrace a homosexual lifestyle as it is to assure idolaters, murderers, adulterers, and thieves that they are safe and secure from all alarm. Nor will it do to say, "Well, we're all idolaters, etc."
