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)
In a brief burst of practical instructions, we learn how to treat church leaders, other church numbers, and everyone else.
If we invest in making disciples, our lives become bound up with theirs to die and live together.
Jesus has authority and power over all things and is bringing the powers of darkness down.
