Chapter 102

This is labeled as a prayer of one afflicted, pouring out his complaint before the Lord.

The first stanza describes the condition of the one praying.  He is really in a bad way.  Too much pain to even eat, bones burning like fire, skin clinging to the bones.  At the end of the stanza, he says it is because of God's indignation.

The second stanza praises the eternity and rule of God over all that is.  It recognizes that God can, and does answer prayer.

The one praying wants his prayer recorded so future generations can see that God answers prayer.  This verse:

16 For the LORD builds up Zion; he appears in his glory; 17 he regards the prayer of the destitute and does not despise their prayer. 18 Let this be recorded for a generation to come, so that a people yet to be created may praise the LORD: [Psa 102:16-18 ESV].

Wouldn't it be nice if the people yet to be created includes us, here in the US, and that He will regard our prayers for this country as he regards prayers for Zion.

This next stanza, the fourth, is short, and asks God not to shorten his days:

24 "O my God," I say, "take me not away in the midst of my days-- you whose years endure throughout all generations!" [Psa 102:24 ESV]

This stanza recognizes that God made all that is, and that even though God's created things will pass away, God Himself will still remain.
