Your kingdom come. Your will be done in earth, as it is in heaven.
All Commentaries on Matthew 6:10 Go To Matthew 6
Augustine of Hippo
AD 430
Or; as by the righteous, so by sinners; as if He had said, As the righteous doThy will, so also may sinners; either by turning to Thee, or in receiving everyman his just reward, which shall be in the last judgment. Or, by the heaven and the earth we may understand the spirit and the flesh. As the Apostle says, “In my mind I obey the law of God,” we see the will of God done in the spirit. But in that change which is promised to the righteous there, “Let thy will be done asin heaven, so in earth;” that is, as the spirit does not resist God, so let the body not resist the spirit. Or; “as in heaven, so in earth,” as in Christ Jesus Himself, so in His Church; as in the Man who did His Father's will, so in the woman who is espoused of Him. And heaven and earth may be suitably understood as husband and wife, seeing it is of the heaven that the earth brings forth her fruits.
De Don. Pers., 3: From this passage is clearly shown against the Pelagians that the beginning of faith is God’s gift, when Holy Church prays for unbelievers that they may begin to have faith. Moreover, seeing it is done already in the Saints, why do they yet pray that it may be done, but that they pray that they may persevere in that they have begun to be?
