For the past few weeks I've been dealing with persistent thoughts that deny the existence of God, deny the divinity of Jesus, or some form of blasphemy. I've these compulsive thoughts before, particularly on the subject of blasphemy. But now I feel like I'm at my wits end. I'm questioning where my thoughts end and where the compulsion begins. It almost feels as though I've lost my faith and I'm scared that I won't be able to come back to God. If I "came back" to God would I actually be with him again or would I have simply tricked myself? I'm not questioning God's existence on a rational level, mind you. Rather, it feels like I'm questioning everything. Can I still call myself a christian or are these thoughts of denial akin to denouncing my faith? Do I actually believe these thoughts . Throughout all of this I'm constantly reminded of Hebrews 6:4-6 and how it is impossible to come again to repentance. Sorry if this is a lot.
