III. “Thy Will Be Done on Earth as It is in Heaven”

From The Catechism of the Catholic Church

2824
In Christ, and through his human will, the will of the Father has been
perfectly fulfilled once for all. Jesus said on entering into this world:
“Lo, I have come to do your will, O God.”⁹⁹ Only Jesus can
say: “I always do what is pleasing to him.”¹⁰⁰ In the prayer
of his agony, he consents totally to this will: “not my will, but yours be
done.”¹⁰¹ For this reason Jesus “gave himself for our sins to
deliver us from the present evil age, according to the will of our God and
Father.”¹⁰² “and by that will we have been sanctified through
the offering of the body of Jesus Christ once for all.”¹⁰³
