What is the Meaning of Nothing?

Nothing is the lack of something. As I look at the verse in Luke 1:37, (”For with God nothing will be impossible”), it makes me contemplate the real significance of nothing. Do I really believe nothing is impossible, or just most things? What are the things I think are not possible for God to do? Do I think my God is not big enough to do all things? It seems obvious to me, if I cannot believe, ‘with God all things are possible,” I have doubt, unbelief or lack of faith.

“But Jesus looked at them and said to them, ‘With men this is impossible, but with God all things are possible.’” Matthew 19:26  NKJV
