2 Kings 1:6
And they said unto him, There came a man up to meet us, and said unto us, Go, turn again unto the king that sent you, and say unto him, Thus saith the LORD, Is it not because there is not a God in Israel, that thou sendest to enquire of Baal-zebub the god of Ekron? therefore thou shalt not come down from that bed on which thou art gone up, but shalt surely die.
After his fall, Ahaziah sent to inquire whether he would recover, seeking an answer about his recovery from Baal-zebub at Ekron instead of inquiring of the God of Israel. That turning from the living God to Baal-zebub, the god of Ekron, was apostasy. Christ sent Elijah to meet the king's messengers on the way and send them back with a rebuke. Elijah answered this apostasy with an earnest protest, rebuking Ahaziah for seeking an oracle from Baal-zebub instead of the God of Israel and asking why the king sought a pagan oracle as if there were no God in Israel.
The message delivered through the messengers announced God's judgment that because Ahaziah had sought an answer from Baal-zebub instead of God in Israel, he would not come down from the bed he had gone up to or recover from his fall. He would not rise from his bed but would surely die there, dying without recovering and dying in the bed he had gone to. Ahaziah's appeal to a pagan oracle declared that he trusted idols more than the true God. That seeking guidance from a false source instead of God dishonors Him, and it dishonored God despite Israel's long experience of His kindness and help.
Ahaziah recognized that the messenger who stopped his servants was Elijah. He knew the announced judgment would come to pass, yet he tried to avert it by sending for the prophet. The warning of death for appealing to Baal-zebub instead of seeking God stands as a warning against turning from God to deceptive spiritual powers. The same kind of idolatry can take a more refined form.
The question of whether there is no God in Israel applies to people in responsible positions who seek lawyers' help for their plans and join with others whose counsel misleads them. It shows they need clearer spiritual discernment. Those who do not test their lives by Scripture and seek God's will in prayer are in danger of being deceived.
