In chapter 5 of Ecclesiastes we are told to "fear God" or revere Him in His greatness.
Ecclesiastes 6:10 & 7:13 describe God's greatness, "consider the work of God, for who is able to straighten what He has bent?" and, "no man can contend with One who is stronger than he."
What lies at the core of our God's immutable nature? Above all else, what should we reverence most about our Great God?
