The gift of saying what I think. For instance, I think it's a bit silly to think that an imaginary super-being gave me anything at all -- gifts or otherwise. What I have I either inherited from my parents or learned along the way.
The least favorite gift God gave me is taking away my total belief in Him for a while. I went through a week where I lost my father, my husband was on the verge of death in another hospital, my unborn baby's life was in question due to a car accident and having no siblings, I had to be the strong one to take care of my mother & grandmother. Instead of turning to God, I blamed Him....I became an agnostic for 2 years.
How I regained by belief in The Father, The Son and The Holy Spirit is very private. All I will say about it is that were it not for my Native American holdings in the Spirit World, I would probably have never regained my faith in God. We know God by many names and He answers us when we call on Him, no matter the name we call Him. I called and He answered.
