1-е Коринфянам 6:18

Flee--The only safety in such temptations is flight (Gen 39:12; Job 31:1). Every sin--The Greek is forcible. "Every sin whatsoever that a man doeth." Every other sin; even gluttony, drunkenness, and self-murder are "without," that is, comparatively external to the body (Mar 7:18; compare Pro 6:30-32). He certainly injures, but he does not alienate the body itself; the sin is not terminated in the body; he rather sins against the perishing accidents of the body (as the "belly," and the body's present temporary organization), and against the soul than against the body in its permanent essence, designed "for the Lord." "But" the fornicator alienates that body which is the Lord's, and makes it one with a harlot's body, and so "sinneth against his own body," that is, against the verity and nature of his body; not a mere effect on the body from without, but a contradiction of the truth of the body, wrought within itself [ALFORD].

In this chapter the apostle, I. Reproves them for going to law with one another about small matters, and bringing the cause before heathen judges (Co1 6:1-8). II. He takes occasion hence to warn them against many gross sins, to which they had been formerly addicted (Co1 6:9-11). III. And, having cautioned them against the abuse of their liberty, he vehemently dehorts them from fornication, by various arguments (Co1 6:12 to the end).

6:18-20 For Christians, the body is the temple of the Holy Spirit (see study note on 3:16-17; cp. 2 Cor 6:16). Sexual sin violates this sacred sanctuary and the divine presence. • You do not belong to yourself: Christians can no longer claim their bodies as their own, as they have been bought . . . with a high price, the blood of Christ (cp. 1 Cor 7:23; Rev 5:9), and every part of their lives has been claimed by Christ for God’s glory (see Rom 14:7-9; 2 Cor 5:14-15).
