My heart and my flesh cries out for the living God

This is the 2nd time that I attended the AACC Mandarin Youth Group's bible study. Today's material is Deuteronomy 12. Many people turned up, even a bit to the surprise of the group leader (Tom).
A very nice and warm gathering for the night. Good sharings too.
Francis led the study. He cited the entire Psalm 94 as an encouraging conclusion.
The 2nd verse caught me: 'My heart and my flesh cries out for the living God'.
Martin Luther, I read somewhere, once wondered at this verse, saying that it is hard to fully comprehend the longing in the Psalmist.
He wrote the following hymn, which I hope I can find the script and learn to sing it:

Out of the Depths

Out of the depths I cry to Thee;
Lord, hear me, I implore Thee!
Bend down Thy gracious ear to me;
I lay my sins before Thee.
If Thou rememberest each misdeed,
If each should have its rightful meed,
Who may abide Thy presence?

Thou grantest pardon through Thy love;
Thy grace alone availeth;
Our works could ne’er our guilt remove;
Yea, e’en the best life faileth.
For none may boast himself of aught,
But must confess Thy grace hath wrought
Whate’er in him is worthy.

And thus my hope is in the Lord,
And not in my own merit;
I rest upon His faithful Word
To them of contrite spirit.
That He is merciful and just,
Here is my comfort and my trust;
His help I wait with patience.

Oh how I miss singing these old hymns, like 'How can it be that I should gain'. It's a pity to see that many overseas Chinese churches favour perhaps too much using 'modern' hymns and almost are giving up the treasures of traditional hymns. How sad. Why shall we simply trade true worship and, especially 'singing with understanding', for emotional satisfaction only? The tune may be trendy, and the beats can be exciting, but after leaving the service, how much do we still remember what we sang, and how often does a song lead us to the true feeling of the presence of our Lord, impossible unless through a deep penitence of our sins?
Let's pray that our Christian songwriters get the true inspiration from above and write more life-touching, not just emotion-arousing, hymns.
"Praise you the Lord. Sing unto the Lord a new song, and his praise in the congregation of saints'. Psalm 149:1
