That is part of our Scripture for this morning -- Micah 6:6-8. The question has been asked about what to bring God -- "burnt offerings, with calves a year old" (v. 6), "rivers of oil, my first born" (v. 7). Micah's reply is "God has already shown you." (v. 8) God is asking for the same thing God has asked for before -- to love God, and neighbor. Jesus reminds us of this in Matthew 22 -- the greatest Commandment(s) - all summed up. Jesus is also reminding the Pharisees of this, in this morning's Gospel reading (Matthew 9:13) - God doesn't require the sacrifice(s) - even the ones listed in the Micah reading - God IS asking us to show "mercy." (Matthew 9:13)
I don't know about you but I don't have "burnt offerings, calves of any age or rivers of oil." I'm definitely not willing to sacrifice "my first born." I'm thinking of modern images - tithes? "extra" money? Are we giving, or trying to give, those instead of actually doing "justice, love kindness and walk humbly with God"? (Micah 6:8) Actually doing something instead of waiting for elected officials to, 'loving' the family member and/or friend who disagrees with you - maybe even voted opposite you, and 'walking' with God - are we really doing these things?
Maybe start small -- a "baby" step -- like actually listening to each other. Or taking the step of faith to "face our giant' and reach out to do a new thing. An important part of "walk humbly with God" (Micah 6:8) is to remember to give God the glory and thanks! Small steps, we can start with small steps!
