Amos 5:6

Amos, as well as the Lord (Amos 5:4), invited the Israelites to seek the Lord by doing good and refraining from evil so they might live (cf. Amos 5:14-15). The alternative would be God’s judgment breaking forth and unquenchably consuming the whole house of Joseph (i.e., the Northern Kingdom, whose main tribe was Ephraim, a son of Joseph).

"Fear of judgment may not be the highest motive for obeying God, but the Lord will accept it." [Note: Ibid.]
