Chapter 2 begins v.1-9 with God at odds with His church (in this case Israel) for their disobedience and worship of idols. Note that God seems to have a hand in the troubles befalling Israel but is not their enemy though angry with them. He does this to bring to their attention and cause their turning from sin.
The second half of Chapter 2; v.10-22 sees the people lamenting their woes, and calls for repentance issued.
The Lord hath done that which he had devised; – Once again we see God is in control of all, sovereign over the events of mankind, here in the Chaldean occupation of Judea, today can we not see His hand in all things restraining the Chaos from unleashing in earnest.
he hath fulfilled his word that he had commanded in the days of old: – God has long promised rewards to those who are faithful and woes to those who are not
he hath thrown down, and hath not pitied: – God is all powerful and here it is demonstrated in the tearing down of walls of Jerusalem, and specifically the Temple of God.
and he hath caused thine enemy to rejoice over thee, – Our enemies rejoice in apparent victory thinking themselves great, but it is He who is greater and will have the final say
he hath set up the horn of thine adversaries. – God has swelled their self-worth, puffed them up and for His purpose (to remind us (Israel) of our place) and set them up for a hard fall in the end
There are clear parallels to Israel and the US found here. Both claim to be established upon Godly principles and laws. Both peoples claim to desire to follow a moral code established by God. Yet both readily and easily turn their backs upon that very same God.
As with Israel, America needs a time of lamenting (a passionate expression of grief or sorrow) and repentance.
