Hi Dave,
There's a couple of things I've learned in my life. You are trying to convince people of things you believe. Sometimes that isn't always possible. If it is the will of God, then it will happen. Take the same advice you gave me. You know in your heart and through your relationship with God and the workings of the Holy Spirit within you what is right. I try not to get into these arguments myself as it ends up upsetting everybody. That surely is not the will of God.
What separates God from man is that He is able to look into our hearts. He sees our pains, our turmoils, and our real motives. I know that God accepts me for who I am. John 3:16 is the crux to the whole matter here. Never doubt your acceptance through the cross, that is the work of the devil.
btw, I have some literature I can pm you if you desire.
