Today's Gospel reading came from Matthew 5. Jesus told his disciples not to swear at all. And that they should let their 'Yes' mean 'Yes' and 'No' mean 'No,' and anything more is from the evil one. It is easy not to be aware of what comes from the evil one and what comes from God. A sharpened conscience is what we need, and we get that as we grow more in union with the Lord.
