During a meal with his disciples in John 13:1-17, Jesus did something that shattered social norms. He dressed like a slave and performed a task that was beneath most slaves by washing his disciples' feet. Although he didn't explain his actions completely, he gave us enough clues to find three important lessons. The first two lessons are about what he can do for us and the third about what we can do for each other. (sermon notes)
Because of God’s work of salvation in us, we need to work out our salvation.
Because of the Holy Spirit, believers can live in a way that pleases God.
Christian thinking is thinking like Jesus, especially as seen in his becoming one of us to die on the cross.
