The secret to obedience is given to us in John’s Gospel, when
Jesus teaches that he is the vine and we are the branches. Our life
depends upon remaining part of him—which we do by being
obedient to his commands and partaking in his Body and Blood
offered in the Eucharist. John in his letter says that we can tell if
we are “abiding” in Christ by our actions: Are they Christ-like?
The power to be like Christ, of course, comes from dying to
ourselves and allowing Christ to live within us. This requires
more than simply listening to or parroting the words of Christ;
this requires a complete abandonment to him.
Every day the official prayer of the Church begins the same
way, by praying Psalm 95: “Come, let us worship the Lord,”
echoes the refrain, inviting us to see our Savior, our Creator, the
God to whom we belong. With the invitation comes a warning:
“If today you hear his voice, harden not your hearts.”
