During Lent God calls us to give up our sin. His pointed attacks against the sins that beset his people help us put off the attitudes and actions of our sinful nature. His perfect righteousness as our substitute assures us that we are right with God and empowers us in godly living. This week Jesus attacks the arrogant attitude that bases its confidence on a superficial connection to God. This sin showed itself prominently among the people of Israel, who believed that their ancestry made them right with God. We too can easily put our confidence in our ancestry, our church affiliation, or our traditions. Instead, we remain right with God by staying currently connected to our Savior Jesus.
