Let me start by saying. It sounds like your dad needs to find Jesus. A true Christian doesn’t hate anyone and we are to be uplifting. Sure he can go through seminary, pass all his classes, but that won’t bring an anointing to his ministry, if he’s not born again. You said you were a believer, what you need to do is pray that the Lord shuts the door on him and puts a stop to it. A good senior pastor will see through him in short order. You need to pray for his salvation most of all. Without Christ as Lord of his life, there is little chance of him changing for the better, and there will be no chance of him going to heaven.
When I became a Christian my dad stopped talking to me, he wanted nothing to do with me. To me that was ok because I didn’t want anything to do with him as well. He was a great guy to the world, but he stunk as a husband and father. Before his death I would tell my brother I would only go back to his funeral just to wiz on his grave. It would be safe to say I hated the man, but God started to do a work in me and before long I came to a place of forgiveness. I understood he was lost and all the things he did to my mother, brother and me, well,,, were a result of that dead spiritual state. My dads died unsaved, pray that your dad gets saved before it’s to late. Take care brother, God bless.
