Amos has to remind the people of Israel that the prophets do not speak for nothing. They proclaim warnings of judgment because God judges his people when they live in sin. The is the same God the New Testament proclaims. Do not attempt to ignore the message of the prophets, living in sin, and use grace as your excuse. That is what Israel did, and they were sorely punished. The lion roared, and they ignored. They would not listen to his loving rebuke. Therefore, they became his prey.
LORD, we fear you. Lead us to safety. Forgive us for ignoring your warnings.
Amos 3
