John 13 marks a significant shift in Jesus' ministry. He's done numerous public signs to prove that He is the Christ and that it is through Him that one may have life. He now shifts to something different.
Sometimes things don't go exactly as we imagine them going. However, God is faithful. We must trust and hope in Him, looking to Him alone for the provision of the Good.
The failure and stubbornness of people in the past didn't prevent God accomplishing His purposes, and it wasn't going to stop Him now. Moses self-perceived deficiencies did not matter. If God calls you to a purpose, He will equip you for it.
God guided the people of Israel out of Egypt and through the wilderness. With this Old Testament backdrop Jesus now proclaims that He is the light of the world. He is the one who guides the people and shows them the way to life.
The miracle of feeding the multitude demonstrates Jesus' superiority to Moses. Moses gave the Israelites manna in the wilderness, yet they died. Jesus, as the bread of life, offers true abiding life.
In an amazing turn of events, God sovereignly guided the process to preserve Moses' life. It would be through Moses that God would deliver his people from bondage.
Despite the racial, gender, and social barriers that would normally prevent a rabbi from speaking to the woman at the well, Jesus shows that the grace of the Messiah has no boundaries.
