1. Though the phrase “God’s authority” may seem unfathomable, God’s authority is not at all abstract. He is present with man every minute of his life, leading him through every day. So, in every person’s day-to-day life he will necessarily see and experience the most tangible aspect of God’s authority. This tangibility is proof enough that God’s authority truly exists, and it fully allows one to recognize and to comprehend the fact that God possesses this authority. God created everything, God created everything, and having created it, He has dominion over all things. In addition to having dominion over all things, He is in control of everything.
2. From the very phrase “God is in control of everything” we should see that what God controls is not a portion of planets, a portion of creation, much less a portion of mankind, but everything: from the massive to the microscopic, from the visible to the invisible, from the stars in the universe to the living things on earth, as well as microorganisms that cannot be seen with the naked eye or beings that exist in other forms. This is the precise definition of the “everything” that God is “in control of,” and is the scope over which God wields His authority, the extent of His sovereignty and rule.
