When people ask me, “What is the cause of homosexuality,” I’ll tell them that the “causes” are as numerous as the stars in the sky. Every person is different, and sexual orientation is a complex thing. There is no one “gay gene,” and the jury is still out on early hormonal influences. No one has been able to eliminate the variety of life experiences that can also contribute to the mix.
So it’s good to learn about the backgrounds of others who have gotten involved in homosexuality, at the least to remind us that people are not easily stuffed into little boxes. Thankfully God isn’t either – and He knows each one of us as well as He does each star in the sky. There are a variety of ways into same-sex attractions and actions, and the Lord has made a way out for each person.
No temptation has overtaken you except what is common to mankind. And God is faithful; He will not let you be tempted beyond what you can bear. But when you are tempted, He will also provide a way out so that you can endure it. 1 Corinthians 10:13
