Jeremiah 7:23-28 is today's first reading. The prophet gave the people the message from the LORD. Let me quote some of the verses.
Walk in all the ways that I command you, so that you may prosper. But they obeyed not, nor did they pay heed. They walked in the hardness of their evil hearts and turned their backs, not their faces, to me. I have sent you untiringly all my servants the prophets, yet they have not obeyed me nor paid heed; they have stiffened their necks and done worse than their fathers. When you speak all these words to them, they will not listen to you either; when you call to them, they will not answer you. Say to them: This is the nation that does not listen to the voice of the LORD, its God, or take correction. Faithfulness has disappeared; the word itself is vanished from their speech.
This above describes today's Western nations well. From Jesus' parable of the tenants (Matthew 21, Luke 20), you learn what would happen to the tenants who mistreated all the servants the owner of the vineyard sent them and killed the son of the owner in the end. To neglect Christ is to neglect your own soul. Reject him and you doom yourself for good.
