In agreement here also. Especially since Isaiah 64 (NASB) says:

6 For all of us have become like one who is unclean,
And all our righteous deeds are like a filthy garment;
And all of us wither like a leaf,
And our iniquities, like the wind, take us away.
7 There is no one who calls on Your name,
Who arouses himself to take hold of You;
For You have hidden Your face from us
And have delivered us into the power of our iniquities.

By the way, I think I like the NASB rendering of this passage better than the NKJV (which speaks of righteousness and rags in the plural). The NASB rendering seems to make a better parallel with our "rightesouness" as a cover verses Christ's righeousness as a cover.

Also, I like the last phrase of verse 7 better, in that it shows that God has delivered us to the power of our own iniquities, while the NKJV says, "For You have hidden Your face from us, and have consumed us because of our iniquities." Why this difference?

True godliness is a sincere feeling which loves God as Father as much as it fears and reverences Him as Lord, embraces His righteousness, and dreads offending Him worse than death~ Calvin
