“Even if you offer me whole burnt offerings and gift offerings,
I will find no pleasure in them; […]
Let justice flow down like waters,
And righteousness like an ever-flowing stream.”
~Amos 5:22, 24

We should not let our sacred service to God fall into a mechanical routine, as if we are doing him a favor through the sacrifices we offer him.
What God really looks for in us is heartfelt obedience. (Ps. 50:14)
False religion allows believers to continue on paths of cruelty and corruption, “absolving” sins through rites and rituals without ever addressing the root of problems. (Amos 2:6,7; 5:12)
Acceptable service to God is motivated by love of what is good.
We should try to reflect his sense of justice. (Amos 5:14,15)
