Come, let us sing to the Lord,
let us shout with joy to the rock of our salvation.
Let us approach him with praise and thanksgiving
and sing joyful songs to the Lord.
For the Lord is the great God,
the great king above all gods.
In his hands are the depths of the earth,
and the heights of the mountains as well.
The sea is his, for he made it,
and the dry land too, which his hands have formed.
O come, let us bow down in worship,
let us kneel before the Lord who made us.
For he is our God,
and we are his people,
the flock he shepherds.
O that today you would listen to his voice!
Do not harden your hearts as at Meribah,
as on the day of Massah in the desert.
There your ancestors tested me,
they tried me though they had seen my works.
For forty years I loathed that generation.
I said, "They are a people whose hearts go astray,
and they do not know my ways."
So I swore in my anger,
"They shall not enter into my rest."
The man of prayer is called continually to approach the Lord with praise and thanksgiving, and to bow down before him in humble adoration. This is the calling of every one; it is the sole reason for which we are created. But not everyone responds to the call. Like everyone who has gone before us, we often harden our hearts and refuse to live as God intends for us to live. And in refusing to live for God we separate ourselves from the only source of true happiness. So we are forever restless and without peace. Yet God's love for us is infinitely greater than our refusal. It is never too late to turn back to the Lord and follow in the way that he lays out for us, the way that leads to happiness both in this earthly life and in the kingdom of heaven. Following the path that leads to the Lord begins by withdrawing from the world and entering into the inner room of the soul where we commune with God in humble prayer. From ancient times the psalms of the Hebrew Bible have provided a model for this prayer.
