We shall be raised therefore, all with our bodies eternal, but not all with bodies alike: for if a man is righteous, he will receive a heavenly body, that he may be able worthily to hold converse with Angels; but if a man is a sinner, he shall receive an eternal body, fitted to endure the penalties of sins, that he may burn eternally in fire, nor ever be consumed. And righteously will God assign this portion to either company; for we do nothing without the body. We blaspheme with the mouth, and with the mouth we pray. With the body we commit fornication, and with the body we keep chastity. With the hand we rob, and by the hand we bestow alms; and the rest in like manner. Since then the body has been our minister in all things, it shall also share with us in the future the fruits of the past.
Therefore, brethren, let us be careful of our bodies, nor misuse them as though not our own. Let us not say like the heretics, that this vesture of the body belongs not to us, but let us be careful of it as our own; for we must give account to the Lord of all things done through the body. Say not, none sees me; think not, that there is no witness of the deed. Human witness oftentimes there is not; but He who fashioned us, an unerring witness, abides faithful in heaven , and beholds what you do. And the stains of sin also remain in the body; for as when a wound has gone deep into the body, even if there has been a healing, the scar remains, so sin wounds soul and body, and the marks of its scars remain in all; and they are removed only from those who receive the washing of Baptism. The past wounds therefore of soul and body God heals by Baptism; against future ones let us one and all jointly guard ourselves, that we may keep this vestment of the body pure, and may not for practising fornication and sensual indulgence or any other sin for a short season, lose the salvation of heaven, but may inherit the eternal kingdom of God; of which may God, of His own grace, deem all of you worthy.
[St. Cyril of Jerusalem, Catechetichal Lectures, 18]
+Lord help us to control our bodies and overcome the lusts of the flesh by dwelling within You. We don’t have the power to fight, but by remembering that we are members of Your Body, we know that you have the power to fight for us, and we have only to ask and You will fight for us. Let us remember the coming Judgement and Resurrection; “Nail Your fear to my flesh, for I have feared Your judgements” (Ps 119:120), Your Holy Fear that we remember how worthless earthly lusts are, and how costly they are.+
