could it possibly be that our faith is not something that can be totally understood, and we just have to trust God on it? Maybe we don't need to fully comprehend every mechanism of God's magnificent Plan for salvation? Maybe?
As a fellow Christian, I would, in as loving a spirit as possible, like to gently point to the scriptures that say our bodies are not our own, but belonging to Christ, must be submitted to him in every way. This includes our sexuality, as difficult as this is. I understand you struggle, and I pray God strengthens you in your journey to true repentance and faith. Praying for You.
