“Know therefore this day, and consider it in thine heart, that the LORD He is God in heaven above, and upon the earth beneath: there is none else.” – Deut. 4:39
Talk about getting “put in your place.”
Know in your mind and consider in your heart: YHWH is the First Cause, the one Infinite Being, the one Omnipotent Power.
The first and the last. There is none else.
