According to St. Gregory the Great, the proof that Jesus knows the Father and is known, in turn, by Jesus, is that He lays down His life for the Father. Unity comes from obedience, and obedience is foundation of unity.
Am I obedient to God? Am I able to submit myself to authority other than my own?
O Holy Spirit, may the unity of the Don with the Father inspire me to be obedient to Jesus. May I imitate Him today in word and deed.
