I should not think it necessary to notice this, the thing is so familiar, were it not that the Lord Jesus hath condescended to use the figure with reference to his grace and power. He calls himself the "Key of David, who openeth and none shutteth; who shutteth and none openeth." (Revelation 3:7; Isaiah 22:22) It is blessed to see in how many ways the Lord manifests the supremacy of his power, He hath the key of heaven, to admit whom he pleaseth: he hath the key of hell, to shut up all his foes; he hath the key of his word, to unfold the mysteries of his kingdom; he hath the key of the heart, to open it, and to render that word effectual. Hence, in all things, from the highest heaven to the lowest hell, Jesus governs. What a sweet thought for all his redeemed to cherish! He it is that opens his church, opens the mouth of his ministers and the souls of his saints, opens the opportunities of ordinances, and gives blessings to ordinances, and the several means of grace upon earth, and finally; fully, and completely opens an entrance for all his redeemed into his everlasting kingdom in heaven. Gracious Lord Jesus, "open thou mine eyes, that I may see the wondrous things of thy law!"
