Another verse for the mix...
Matthew 7:11
"If ye then, being evil, know how to give good gifts unto your children, how much more shall your Father which is in heaven give good things to them that ask him?"
Christ affirms that we are evil. It is a blanket statement.
He also affirms that we are able to do good.
Seems like the two ideas need to be held in tension and are not contradictory.
Common grace.
