Ezra Stiles Ely answers the question: “Who is this King of glory?”
“To such as might demand, ‘Who is this king of glory? the Spirit of the Lord has said, though he should appear in the form of a servant, meek, and sitting on an ass, yet he is ‘Jehovah, strong and mighty; Jehovah, mighty in battle.’ The Saviour whom the church is called upon to receive, is declared to be God as well as man; to be strong to rule and defend; to be mighty to save, and mighty to overcome rebel legions of men and angels in battle. Receive him, who shall conquer sin, death, and hell, O ye sons of men, for your Saviour.
It is no less the duty of the visible church to receive Jesus now as Jehovah, who comes in spirit, the Conqueror and Redeemer, than it was her duty to receive him when he came in the flesh.
Behold, he stands at the door of the human heart, and knocks for admittance. He calls to the sons of men. Open your hearts to receive the brightness of the Father’s glory. Do you ask after his character who demands admission to your thoughts, your affections, and all the secret springs of your action? It is the Lord Jesus, who has a strong arm, to save, or to destroy.” — Ezra Stiles Ely, A Lecture on the Twenty-Fourth Psalm (1822)
