We of Alcoholics Anonymous have each experienced these. We do not even need to believe that God is working in our lives, God will still create the most beautiful works of healing and love. He is very capable of working anonymously, never seeking credit. And that is a good thing because most of us puff up our chests and talk loudly of all of our "work" that got and keeps us sober.
I am so incredibly grateful for God's infinite mercy and love. I could "work" for a lifetime and never come close to earning what I have been so freely given.
