11 But in order that the amendment may take place the more quickly, do this which I tell you. Inscribe upon the wall of your house, and upon the wall of your heart, that “flying sickle;” and think that it is flying forth on occasion of the curse, and constantly remember it. And if you observe another person swearing, restrain, forbid, and be careful for him, and be careful for your own domestics. For if we would look to this, that we might not merely correct ourselves, but also bring others to the same point, we shall ourselves quickly arrive at the goal; since while we undertake to instruct others, we shall be ashamed and blush, should we in our own case seem to leave those things unperformed, which we enjoin upon them.
There is no need to say more; for much has been already spoken on these matters; and these things are now said only by way of remembrance. But may God, who is more sparing of our souls than we are, make us perfect in this, and every good work; that so having completed the whole fruit of righteousness, we may be found worthy of the kingdom of heaven, through the grace and lovingkindness of our Lord Jesus Christ, through Whom, and with Whom, to the Father, with the Holy Ghost, be glory, for ever and ever. Amen.
