Amos 5:21-24 really talks about what matters to God:
I hate all your show and pretense-the hypocrisy of your religious festivals and solemn assemblies. I will not accept your burnt offerings and grain offerings. I won't even notice all your choice peace offerings. Away with your noisy hymns of praise! I will not listen to the music of your harps. Instead, I want to see a mighty flood of justice, an endless river of righteous living.
Whenever you see the word "justice" in the Bible it is usually in regards to caring for people's needs. Living a "righteous life" means doing it God's way.
God wants us to take care of others and live a Christ-honoring life - a radical concept by most standards of "church". By the way, church, He means do this every single day - not just on Sunday (or when the Pastor is looking).
Always be the church that matters to God. Amen?
