“Thus says the Lord: ‘What wrong did your fathers find in me that they went far from me, and went after worthlessness, and became worthless?'” (Jeremiah 2:5, ESV).
The prophet Jeremiah was called to prophesy to the people of Jerusalem during the reign of King Josiah and until the city’s final fall to the Babylonians. Jeremiah preached Old Testament themes in a fresh way. His unique theological contribution as an Old Testament prophet was his articulation of the new covenant between God and humanity (see Jeremiah 31:31-34).
Jeremiah emphasized that God’s chosen people, Israel with whom God had made a special covenant, had forsaken Him and chosen to worship other gods. In this verse Jeremiah claimed that instead of seeking God, the Israelites were going after worthless idols.
Instead of seeking God, which was worthwhile, they tried to find spirituality in idols, which were worthless. And, by seeking after that which was worthless their lives consequently became worthless.
You are what you wish for–rather, you become what you wish for–according to Jeremiah.
