The argument of the Apostle Paul in Romans chapters 1-3 appears to have much bearing on this debate.
In chapter 1, Paul brings up how sinful humankind alienated from God can fall into sins like unnatural sexual unions, stating:
God handed them over to degrading passions. Their females exchanged natural relations for unnatural, and the males likewise gave up natural relations with females and burned with lust for one another. Males did shameful things with males and thus received in their own persons the due penalty for their perversity…Although they know the just decree of God that all who practice such things deserve death, they not only do them but give approval to those who practice them.—Romans 1.24-28, 32.
That phrase in the last verse, “that all who practice such things deserve death” is interesting. It applies not only to those engaged in homosexual activity but notice the full context:
They are filled with every form of wickedness, evil, greed, and malice; full of envy, murder, rivalry, treachery, and spite. They are gossips and scandalmongers and they hate God. They are insolent, haughty, boastful, ingenious in their wickedness, and rebellious toward their parents. They are senseless, faithless, heartless, ruthless. Although they know the just decree of God that all who practice such things deserve death, they not only do them but give approval to those who practice them—Romans 1.29-32.
Notice the list. Have we ever envied another? Been rivals of another? Have we ever participated in the flow of gossip, starting it or listening to it or repeating it? Have we ever boasted about ourselves? Ever been rebellious or disobedient to our parents? Have we ever lacked faith?
If we have, then we are no different than those who engage in homosexual acts, for “the just decree of God [is] that all who practice such things deserve death.”
So tell me? What does it matter if a person is born with a homosexual inclination or not? Are you who are born without one any better off? Have you never read the Scripture that says: “By the standard by which you judge another you condemn yourself, since you, the judge, do the very same things.” And what things are those? Merely the “shameful things” of Romans 1.24-28? No, but all things mentioned from verse 24 to verse 32!
“Do you suppose, then, you who judge those who engage in such things and yet do them yourself, that you will escape the judgment of God? Or do you hold his priceless kindness, forbearance, and patience in low esteem, unaware that the kindness of God would lead you to repentance?” (Romans 2.1-4) If in God’s forbearance, patience, and mercy he has not judged the homosexual by bringing them all to their death, who are you guilty of the sins from the same list to be engaging in debate over this? Do you not believe that the mercy of God in Christ will save the envious, the gossips, the haughty, boastful, and faithless rebellious children that you are? If God will save you, deserving of death, what does it matter if God saves someone else equally deserving of death? Or do you believe that he will not or cannot?
Who cares if a person is born as a homosexual or not? Have you so little faith in the mercy of God in Christ? If God chooses to give to you, someone who has labored much and never turned away from him, and also chooses to save another who has not labored as you and has turned away, is that not a reason for rejoicing and boasting about God?—Read Luke 15.11-32 and compare it with Matthew 20.1-16.
