Is someone born gay? Does God create homosexuals?

No, someone is not born gay or created by God to be homosexual.  God does not tempt anyone with sin or evil (James 1:13-15), such as the sin of homosexuality (Romans 1:24-32, Genesis 19 , Leviticus  18:22 ; 20:13, 1 Corinthians 6:9-11, Galatians 5:19-21, Ephesians 5:3-3 , 1 Timothy 1:9,10 , Jude 7).  Just as there is no genetic excuse for anger, murder, lust, adultery, greed, theft, or lying, there is no genetic excuse for homosexuality or any other sin.
Everyone is born with inherited sin with both guilt of and inclination towards sin (Romans 5:12, Jeremiah 17:9, Psalm 51:3-5).  We all then choose to sin against our Creator by failing to treasure and value God above any other thing.  We all morally rebel against God’s commands and will be held accountable according to His perfect, Holy standard (Romans 3:10-12, 23).
Our family and cultural environment may influence us toward a particular type of sin, but sin is ultimately a personal choice of law breaking that we make.  We should not be surprised or shocked when non-believers do not understand God’s truths or yield to obey His plans.  Such ongoing submission to and choice of sin as their practice and identity reveals their lost state.

What does the Bible say about homosexuality?

Homosexuality is repeatedly condemned as sin without qualification or nuance. Romans 1:24-32, Genesis 19 , Leviticus  18:22 ; 20:13, 1 Corinthians 6:9-11 , Galatians 5:19-21 , Ephesians 5:3-6, 1 Timothy 1:9,10 , Jude 7.
For this reason God gave them up to dishonorable passions.  For their women exchanged natural relations for those that are contrary to nature; [27] and the men likewise gave up natural relations with women and were consumed with passion for one another, men committing shameless acts with men and receiving in themselves the due penalty for their error.  [28] And since they did not see fit to acknowledge God, God gave them up to a debased mind to do what ought not to be done.  (Romans 1:26-28)
Homosexuality is the embracing and practice of same-sex lusts, desires, acts, pride, and identity. Homosexuality is contrary to God’s portrayal of the Gospel in marriage and is contrary to His creation of nature, physically, anatomically, reproductively, and a perversion of His plan for sexual pleasure.

• 1 Corinthians 6:9 – ESV “nor men who practice homosexuality” (refers to passive & active partners in homosexual acts)
• Malakos (Greek) – effeminate, of a boy kept for homosexual relations with a man, submits his body to unnatural lewdness
• Arsenokoites (Greek) – homosexual, one who lies with a male as with a female, sodomite, homosexual (1 Tim 1:10, 1 Cor 6:9)

This is not a new or modern day issue.  Paul writes to Christians in Corinth, saying (to include reference to the sin of homosexuality), “And such were some of you. But you were washed, you were sanctified, you were justified in the name of the Lord Jesus Christ and by the Spirit of our God.” (1 Corinthians 6:11).

Is God Anti-Gay ?

Is God anti-gay?  
No, but God is against everyone who lives for and values themselves more than God (Ezra 8:22).  For those who embrace the identity of “homosexual,” “lesbian,” “gay,” “bisexual,” “transgender,” or “queer,” they have chosen an identity apart from God (1 John 3:9-10).  God is against their sin (Romans 3:10-12,23), and they are storing up His wrath for themselves (Romans 2:5).  The good news is that God is patient towards us, “not wishing that any should perish, but that all should reach repentance” (2 Peter 3:9, 1 Timothy 2:4).  God shows us His amazing love through the sacrificial, substitutionary death of His Son Jesus on the Cross while we were still choosing to live life our own way (Romans 5:6-11).  God wants everyone who has chosen the identity of gay to admit and turn from their sin, believe He lovingly died on the Cross and rose from the grave, and confess Christ as Lord (Romans 10:9-10).
God “desires that all people to be saved and to come to the knowledge of the truth.” (1 Timothy 2:4)
The Lord is not slow to fulfill his promise as some count slowness, but is patient toward you, not wishing that any should perish, but that all should reach repentance. (2 Peter 3:9)

What Does the Bible Say About Marriage ?

Let marriage be held in honor among all, and let the marriage bed be undefiled, for God will judge the sexually immoral and adulterous. (Hebrews 13:4, ESV)

Or do you not know that the unrighteous will not inherit the kingdom of God? Do not be deceived: neither the sexually immoral, nor idolaters, nor adulterers, nor men who practice homosexuality (1 Corinthians 6:9)
If a man lies with a male as with a woman, both of them have committed an abomination (Leviticus 20:13)

“If your opinion about anything contradicts God’s Word, guess which one is wrong?” Rick Warren“There is a way that seems right to a man, but its end is the way to death.” (Proverbs 14:12)
