There's no use fighting it. The prophets in the Bible would disagree. They stride into Hebrew history and announce, in no uncertain terms, that there is one God in this universe, and this God is not neutral on matters of good and evil. This God places moral demands on human beings, and holds us accountable for our lives. Amos is the earliest of Israel's prophets from whom we have a book of writings.
Nobody likes to hear about evil and injustice, especially when times are good.
Being a prophet of God is always a lonely job. Amos comes onto the scene during one of the most prosperous periods of Jewish history. But Amos can't help but see that within this outward peace there is a creeping rottenness at the core of society that will bring destruction in the end. He sees a people that has become self-indulgent and soft, and leaders who are increasingly corrupt. Our prosperity is not going to last.
