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 confronts a misplaced sense of security. No sooner are we assured of God's love than we are tempted to think that we have done something to earn or deserve it. We must always remember the importance of repentance. If we think we are standing firm because of our character or merit, we are in danger of falling. Thankfully, God graciously gives us time to turn to him and trust in his mercy.
