With Amos, the modern Christian must believe and proclaim that a prosperous economy cannot be built on a unjust society, because the foundation of peace and prosperity can be only justice, and especially justice that is built upon the acknowledgement that God is God and we are not.
Whatever strength you feel you possess that you can boast in, God does not think much of it. God is not against your strengths and talents, but when you rely on them rather than on him to secure and defend your prosperity, God says that all your excellence, all that in which you would take pride, is nothing next to his power. Your mighty fortress will not secure you against his justice.
What we do for God is important and God appreciates it and takes it seriously. However, unless we are treating our fellow humans with fairness, kindness, and generosity, God doesn’t have any use for our tithes and offerings.
The question Amos 5:1-7 poses to us today is this: where are we seeking our security? Are we, like Israel, confusing human institutions for the activity of God in the world? Are we conflating the Kingdom of God and the kingdoms of the earth?
