In today's Gospel, Jesus prays his high priestly prayer, the essence of which is that God the Father would protect us from sin and Satan, so we can become saints. Our Lord says the basis of our being made holy is that he made himself holy by being perfectly obedient to the Father, an obedience that went all the way to his death on the Cross: "And I consecrate myself for them, so that they also may be consecrated in truth".
It is this same prayer that Jesus prays for us at the right hand of the Father in heaven and at every Mass; for at every Mass, our Lord offers himself to the Father under the sacramental signs of bread and wine, so that we might receive the grace of the Holy Spirit from the Father through the words and actions of the Sacred Liturgy, but above all, in the Blessed Sacrament. This grace is given to us, so we might offer ourselves to the Father "through him, with him, and in him".
May the Lord always dispose our hearts to receive his grace every moment of our lives, but above all when we participate in the Divine Liturgy.
