Eliyahu’s words imply that the nation had not abandoned the service of God, but did not serve Him exclusively. Rather, they attached elements of Ba'al worship to their worship of God. On the account of the nation’s acceptance of the challenge between him and the prophets of Ba’al, Eliyahu’s opponents are forced to accept. Eliyahu is attempting now to come close to the nation and therefore does not mention the drought as its harsh results are a sore point for the nation.
