So He said to them, “When you pray, say:
Our Father in heaven,
Hallowed be Your name.
Your kingdom come.
Your will be done (Luke 11:2)
Saint Gregory of Nyssa: “Now the will of God is the salvation of men. If therefore we prepare to say to God, ‘Thy will be done also in me,’ it is absolutely necessary first to renounce that which was contrary to the divine will and to give a full account of it in confession….When Thy will is done in me, every foul and wicked movement of my free will is brought to nought….If we have an inclination towards something good we need God to carry the desire into effect. Therefore we say: ‘Because Thy will is temperance, but I am carnal and sold under sin, may this good will be accomplished in me by Thy power’; and so it is also with justice, piety, and deliverance from passions.” [The Lord’s Prayer, Sermon 4, 58-60.]
