What does Paul mean when he says that we have all together “become worthless”?  (3:12)  How do we reconcile that reality with the doctrine that all people are made in God’s image, and therefore have inherent dignity and worth?  (Genesis 1:27-31, Genesis 2:7)

What does 3:13-14 (quoted from Psalm 5:9, Psalm 140:3, Psalm 10:7) teach about  the importance of (and the potential danger of) our words?  Why is it important for us, as Christians, to be careful with what we say, and to guard our words diligently?  What are some ways that we can sin with our words?

What does Paul mean when he says that “every mouth will be stopped”?  (3:19)  Why is it important that we be silent before God when he renders his verdict of judgment against us?  What kind of heart posture does that imply?
