If it is, you are closer to the priest Amaziah than the prophet Amos in this passage. And you need to heed the message of Amos. God is not pleased with your false religion. Israel took on the worship of other gods. They no longer saw Yahweh as uniquely the only true God.
Faith is a matter of personal choice.
You can tailor make your own religion. I hear Christians today, both Catholic and Protestant, declaring that it doesn't really matter if people go on worshipping their own gods. That in the end, God will accept them. It is unpopular to say that Jesus is the only way to God. But we must believe it, and if we have stopped believing it, we must repent of that.
