The readings for the first Thursday of Advent:
In that day shall this song be sung in the land of Judah; We have a strong city; salvation will God appoint for walls and bulwarks.
Open ye the gates, that the righteous nation which keepeth the truth may enter in.
Thou wilt keep him in perfect peace, whose mind is stayed on thee: because he trusteth in thee.
Trust ye in the Lord for ever: for in the Lord Jehovah is everlasting strength:
For he bringeth down them that dwell on high; the lofty city, he layeth it low; he layeth it low, even to the ground; he bringeth it even to the dust.
The foot shall tread it down, even the feet of the poor, and the steps of the needy. (Isaiah 26:1-6, KJV)
Not every one that saith unto me, Lord, Lord, shall enter into the kingdom of heaven; but he that doeth the will of my Father which is in heaven. . . .
Therefore whosoever heareth these sayings of mine, and doeth them, I will liken him unto a wise man, which built his house upon a rock:
And the rain descended, and the floods came, and the winds blew, and beat upon that house; and it fell not: for it was founded upon a rock.
And every one that heareth these sayings of mine, and doeth them not, shall be likened unto a foolish man, which built his house upon the sand:
And the rain descended, and the floods came, and the winds blew, and beat upon that house; and it fell: and great was the fall of it. (Matthew 7:21, 24-27)
