What can we learn from people who worship idols about faithfulness? It sounds backward, but God uses this comparison to expose His people's deep sin.
The core of Jeremiah's message in this passage is a stark contrast between the religious practices of the surrounding nations and Israel's actions.
The Steadfast Heathen
The call to search 'Chittim' and 'Kedar' is to find nations that, despite worshipping gods that 'are yet no gods' (Jeremiah 2:11), maintained a remarkable consistency. These nations, whether from the sophisticated West or the nomadic East, generally stuck with the gods their ancestors had passed down. Their devotion to false deities, while misguided, demonstrated a loyalty and stability that Israel lacked.
The Faithless People of God
Israel, on the other hand, had 'changed their glory for that which doth not profit' (Jeremiah 2:11). They abandoned the true God – the God who had revealed Himself, given them life, and sustained them. He was their 'glory,' their highest honor and source of strength. To exchange Him for lifeless idols was not just a change of gods; it was a catastrophic devaluation of the ultimate Good.
