"I will lay the Key of the House of David upon His shoulder" (Is. XXII. 22). "To the Angel of the Church of Philadelphia write: These things saith the Holy One and the True One, He that hath the Key of David, He that openeth and no man shutteth, shutteth and no man openeth: I know thy works. Behold I have given before thee a door opened which no man can shut, because thou hast a little strength." (Apoc. III. 7-8). The Babe unborn has already had the Key laid upon His Shoulder. He already has authority. Soon, very soon now, He will come to use it. How will He use this Key and what is it? It is the Key of authority but it is also the Key of love. (1) He is coming to unlock the gates which hold the human race fast in ignorance and sin, to be its Redeemer, to give it "a door opened which no man can shut," to give it a chance if it will of walking out of its prison-house into the liberty wherewith Christ alone can make it free (Gal. IV. 31). (2) He is coming to put His golden Key of love into the hearts of men, to open those doors which are shut against Him and which none but He can open, for none but He can give grace. Each little child whose heart is filled with grace at its Baptism is only able to receive it because the little Child with the golden Key has opened its heart. "Thou hast opened the Kingdom of Heaven to all believers." Come, then, O Key of David, come and begin Thy blessed work on earth. Thou hast already put Thy magic Key into the heart of St. John the Baptist and doubtless of many another; come and tarry not, come and found Thy Church and pass on the wondrous power of the keys to those with whom Thou wilt leave Thy authority. (3) He is coming to open with His Key of love His own most Sacred Heart. None but He can open that vast treasure-house of love, and none but He can shut it. It will be there for a refuge for all His children in all time--a standing memorial of His love. What does He ask in return? Only that when we hear Him put His golden Key into our hearts, there may be a response: "My Beloved put His Hand through the key-hole and my heart was moved at His touch. I arose up to open to my Beloved" (Cant. V. 4-5). The rising up to let Him in is our part, He puts in His Key and unlocks, that is, He removes all obstacles by His grace, but we must respond to that grace for though He has unlocked the door He will not force an entrance. "Behold I stand at the door and knock," and then He waits, waits for our correspondence and for our love. "My son, give Me thy heart," He wants it, He has used His Key of love to obtain it, but He will not take it, it must be a free gift of love. At the last great Advent the door of His mercy will be shut against all those who have refused Him an entrance into their hearts, and when He shuts, no man can open. "Lord, Lord, open to us," and the answer will come through the eternally locked door: "I never knew you, depart from Me."
