God is putting fire in Jer's bones. A consuming call. When fire is within us, we are consumed. Jer felt the fire. He answered the call.
Fire can smoulder just so long, and it breaks forth.
The cold reception of the message in our world, a message that fails to consumes hearts, is explained by the cold reception of the message in the church of Christ, the very people of God. The spir ignorance of our world is explained by the spir ignorance among us. A convicting call. We do not know how the prophet died, but we do not he was convicted and answered the call of God even in the face of death and persecution by his countrymen. A Jewish story accepted by early Xns says Jer died in Taphnes, stoned by his own people.
