God is

Hebrews 11:6 “But without faith it is impossible to please Him: for he that cometh to God must believe that He is, and that He is a rewarder of them that diligently seek Him.”

“I know whom I have believed.” (Latin – Scio cui credidi) - Blaise Pascal 
Life has meaning and purpose because our Creator and Savior is, and in that fact, I can keep calm.

1 Corinthians 8:6 “There is one God, the Father, from whom are all things and for whom we exist, and one Lord, Jesus Christ, through whom are all things and through whom we exist.”

God is.
