Isaiah 26:1-6 (NIV)

A Song of Praise

26 In that day this song will be sung in the land of Judah:

We have a strong city;
    God makes salvation
    its walls and ramparts.
2 Open the gates
    that the righteous nation may enter,
    the nation that keeps faith.
3 You will keep in perfect peace
    those whose minds are steadfast,
    because they trust in you.
4 Trust in the Lord forever,
    for the Lord, the Lord himself, is the Rock eternal.
5 He humbles those who dwell on high,
    he lays the lofty city low;
he levels it to the ground
    and casts it down to the dust.
6 Feet trample it down—
    the feet of the oppressed,
    the footsteps of the poor.

Matthew 7:21 (NIV)

True and False Disciples

21 “Not everyone who says to me, ‘Lord, Lord,’ will enter the kingdom of heaven, but only the one who does the will of my Father who is in heaven.

Matthew 7:24-27 (NIV)

The Wise and Foolish Builders

24 “Therefore everyone who hears these words of mine and puts them into practice is like a wise man who built his house on the rock. 25 The rain came down, the streams rose, and the winds blew and beat against that house; yet it did not fall, because it had its foundation on the rock. 26 But everyone who hears these words of mine and does not put them into practice is like a foolish man who built his house on sand. 27 The rain came down, the streams rose, and the winds blew and beat against that house, and it fell with a great crash.”
