Hi,
Just like to say that Keith, I have had the same sort of thing happen to me in regards to not feeling the fire of the Lord.
I may not have been a christian for a very long time, but I feel that God has already used me and is preparing me for the greater things that are yet to come.
Last year, I was having literal spiritual attacks and many family and personal issues were all dumped onto me in the space of a few months, which made me almost give up my hope in God, my fire was burnt out, only the embers left, almost out.
I wanted to end it all, because I though that surely if God was truely a God of healing and restoration, and miracles he could simply breathe his love and grace into my situation.
This is when I became angey with God, blaming him for everything that had happened.
It wasn't until God started peeling back layer and layer and the wall of my self pride was broken down, and I found my self at the front of the church at the end of the service, this is when God starting his healing work in my life, and I knew that things were going to be different. I slowly started finding ways to deal with all my family issues etc, which restored my hope in the Lord, and it felt like a can of gasoline, and a fresh match was lit in my heart. Don't give up. Keep on pushing through, because in the darkest hour, that is when triumphs happen.
