"Yours, O Lord, is the greatness and the power and the glory and the victory and the majesty, indeed everything that is in the heavens and the earth; Yours is the dominion, O Lord, and You exalt Yourself as head over all."
He belongs everything in this earth. He is the head of over all dominions here in this world. The Kingdom is also His. Indeed everything that is in the heavens and on the earth, it is His.
That is how sovereign the Lord is. He is indeed mighty and worthy to be exalted. He is worthy to be bowed down and to be adored. His love is indeed as vast as the universe because He made it beautiful for us. His creations are always perfect.
