But amongst these marvellous works of Divine Providence it yields us satisfaction to mark, how, for the enlightening the night of this present life, each star in its turn appears in the face of Heaven, until that towards the end of the night the Redeemer of mankind ariseth like the true Morning Star; for the space of night, being enlightened by the stars as they set and rise in their courses, is passed with the heavens in exceeding beauty. Thus in order that the ray of stars, darting forth at its appointed time, and changed in succession, might reach the darkness of our night, Abel comes to shew us innocency; Enoch, to teach purity of practice; Noah, to win admittance for lessons of endurance in hope and in work; Abraham, to manifest obedience; Isaac, to shew an example of chastity in wedded life; Jacob, to introduce patience in labour; Joseph, for the repaying evil with the favour of a good turn; Moses, for the shewing forth of mildness; Joshua, to form us to confidence against difficulties; Job, to shew patience amid afflictions. Lo what lustrous stars see we in the sky, that the foot of practice may never stumble as we walk this our night's journey; since for so many Saints as God's Providence set forth to man's cognizance, He, as it were, sent just so many stars into the sky, over the darkness of erring man, till the true Morning Star should rise, Who, being the herald to us of the eternal morning, should outshine the other stars by the radiance of His Divinity.
