And the fact is that we are ALL slaves to sin.
John 8: 34-36
Jesus answered them, “Truly, truly, I say to you, everyone who practices sin is a slaveb to sin. 35The slave does not remain in the house forever; the son remains forever. 36So if the Son sets you free, you will be free indeed".
The fact is that we live in an evil world and are afflicted with the condition known as "sin" and we are INCAPABLE of not sinning.
1 John 5:19 esv
We know that we are from God, and the whole world lies in the power of the evil one.
Romans 7:18 esv
For I know that nothing good dwells in me, that is, in my flesh. For I have the desire to do what is right, but not the ability to carry it out.
My belief is that demonic and Satanic oppression is what pushes or compels us to engage in sin and, for some, that means engaging in homosexual behavior, for others it might mean getting drunk every night. It's all sin!
Ephesians 6:12 esv
For we do not wrestle against flesh and blood, but against the rulers, against the authorities, against the cosmic powers over this present darkness, against the spiritual forces of evil in the heavenly places.
We are responsible for our sins, but only to a point because ultimately, we cannot help but sin. We must try to resist sin, of course, but God has forgiven us for our sin as evidenced by the sacrifice of Jesus for ALL of mankind.
So, when people tell you that gay people have a "choice" to NOT be gay, that's not exactly true. Again, they have as much "choice" to not be gay as the critic does to not engage in sin.
