Words of Jeremiah

I'm currently reading through the book of Jeremiah. It's such a sad book. But at the same time, it's such a revealing book. It shows a God who feels, who hurts for His people. So many cries and pleadings to repent and return to what they were made for. This passage in chapter 2 really caught my attention:

"Go west and look in the land of Cyprus;
go east and search through the land of Kedar.
Has anyone ever heard of anything as strange as this?
Has any nation ever traded its gods for new ones,
even though they are not gods at all?
Yet my people have exchanged their glorious God
for worthless idols!
The heavens are shocked at such a thing
and shrink back in horror and dismay,"
says the LORD.
"For my people have done two evil things:
They have abandoned me--
the fountain of living water.
And they have dug for themselves cracked cisterns
that can hold no water at all!"

When we sin and turn away from the LORD and His purpose for us, I think it's fair to ask, is there anything as strange as this? Why would His people, whom he created and loves and protects, want to turn away from Him to other gods that they know are false and won't bring satisfaction. We are a silly people. We are truly strange.
