Righteousness vs. Wickedness
This Psalm seems to be about wickedness versus righteousness and how God loves righteousness and justice and hates wickedness. This concept is obviously very familiar. This makes me think about the ultimate irony of sin, particularly amongst believers. We know that God sees everything and examines everything (check out verse 4), but we still sin. I guess this is why we really need(ed) Jesus and the sacrifice he made for us.
