Hello dre91,
I know there are brothers and sisters here on the forum who's married to an unbeliever and can emphathize more so than I. However, I know it's an awful feeling to be rejected by those you love dearly. It's even more painful when they surmise your love for God is caused by a demonic influence. Though it was hard for me to accept, I begin to understand that this was only proof that God was doing something different with me. Peter warns us not to be surprised when these hard trials come upon us as though something strange were happening [1 Peter 4:12]. Jesus said that he didn't come to bring peace, but a sword. He even said there will come a time when your enemies will be they of your own household [Matthew 10:34-36].
I know it's very hard because pratically my whole family has significant roles in the pentecostal church and they all look at me with grave disdain. Imagine how it feels to have such a love for God only to be look upon as Satan himself and/or a heretic. My father disapproves of me, my mother disdains me, my aunt thinks I'm the archangel for Satan, and the list goes on. I experience this just about everyday in one form or another. I say this because I want you to know that God will give you peace in this situation. One day you will begin to see the pain you're experiencing can't even scratch the surface in comparison to who you are in Christ and the reward God has waiting for those predestined to be conformed to the image of the Son of God. Again, I know it hurts but one day you'll appreciate the tears you've cried.
Be encouraged dre91 and I'm praying for you,
Charles
