Thankful means...

...submission.

It means I acknowledge there is a God that provides all that I need to survive. I recognize that He gives abundantly more than I need. He satisfies my physical, emotional, and spiritual needs.

I am thankful because I have no power to do it myself. I must depend on God for life itself. I have learned that the whole universe above me and around me is intricately designed to sustain me.

I have faith in this God to provide for my future throughout eternity. He has provided a way of salvation from the punishment of sin. He is making a place for me in Heaven. I need not fear, for He is my everything.
