Ken's sermon explores Jesus' teachings on Kingdom righteousness from Matthew 5:38-48, focusing on how to respond to insults, lawsuits, and enemies with unexpected grace and kindness. He emphasizes that Jesus reinterprets the "eye for an eye" law, encouraging believers to show grace as their first impulse rather than retaliation or resistance. The sermon concludes by linking these teachings to God's perfect love for all people, exemplified ultimately in Christ's sacrifice on the cross.
