Obedience is not impossible.
“Indeed, the sons of Jonadab the son of Rechab have observed the command of their father which he commanded them, but this people [Judah] has not listened to Me.” (35:16)
The LORD blessed this family for their example of obedience. Sojourners in the land, not claiming any certain deity or religion, simply obeying their family patriarch.
“Therefore says the LORD of hosts, the God of Israel, ‘Jonadab the son of Rechab shall not lack a man to stand before Me always’.” (35:19)
He introduced Himself with a blessing. Then, went on to make a final plea:
“Perhaps the house of Judah will hear all the calamity which I plan to bring on them, in order that every man will turn from his evil way; then I will forgive their iniquity and their sin.” (36:3)
This warning caused quite the buzz, but was ultimately rejected (burned) by the king.
There’s a lot here, from the relationship The LORD has with foreigners, to the harsh judgment He brings on those who lead His people badly.
What sticks out to me is His justice paired with patience. He creates every opportunity for redemption. His pursuit is relentless and His expectations are reasonable. He sees what people do with the information they have and proceeds accordingly, in righteousness and loving kindness.
We are accountable to what we know, which begs the question: what have I done with the information I’ve received?
