Amos 4:4-5

Amos 4:4-5
"Go to Bethel and sin;
go to Gilgal and sin yet more.
Bring your sacrifices every morning,
your tithes every three years.

Burn leavened bread as a thank offering
and brag about your freewill offerings—
boast about them, you Israelites,
for this is what you love to do,"
declares the Sovereign LORD.

When I read this, I was struck by how it can be read with sarcasm. Did God say it sarcastically or is that just me reading it that way?

God goes on to talk about how no matter what He did, the Israelites would not return to Him. This got me thinking, how often have I sinned (strayed from God) and yet continue to tithe or do the right stuff on the outside without really returning to God? What would God say to me? What would He say to you?
