“Flee fornication. Every sin that a man doeth is without the body; but he that committeth fornication sinneth against his own body …. For this is the will of God, even your sanctification, that ye should abstain from fornication” (1 Corinthians 6:18; 1 Thessalonians 4:3), says the Scripture. When the apostles and the elders gathered together at Jerusalem to discuss whether it was lawful to command the Gentiles to keep the law of Moses or not, it seemed good to the Holy Spirit to command the brethren who were of the Gentiles to abstain from things offered to idols, from blood, from things strangled and from fornication (Acts 15:20).

Fornication is the sexual intercourse between an unmarried man and an unmarried woman. Therefore, if a man has sexual intercourse with his fiancée, both of them commit fornication, because in the sight of God a man can have sexual intercourse only with his wife, as it is written: “Therefore a man shall leave his father and mother and be joined to his wife, and they shall become one flesh” (Genesis 2:24 – NKJV). Note that God said: ‘He will be joined to his wife’ and not ‘He will be joined to his fiancée’, in order to understand that God commanded that a man should have sexual intercourse only with his wife. But the world, which has perverted the straight ways of the Lord, doesn’t think so, for it encourages the sexual intercourse between the betrothed, as if it were a right thing which they are allowed to do, as if there were no offence in it. Those who raise their voice against the sexual intercourse between the betrothed are called ‘people full of taboos who refuse to conform themselves to the times’. Well, yes, we refuse to conform ourselves to this present evil age; we refuse to call evil good. It is crazy to call what the Creator said it is harmful for man and woman a good thing; the God who made the human body and put into it the breath of life knows very well what is good for man and what is harmful for him. Sex before marriage produces a sense of guilt because it is sin (instead, sex does not produce any sense of guilt after marriage). For this reason we, as believers, refuse to listen to those who pass fornication off as a lawful and beneficial thing, because they boast and lie against the truth, being full of selfish ambition. God cannot lie, and if He said through Paul: “Flee fornication”, it is because He knows the evil consequences of fornication and He wants to spare us all kinds of troubles and pains. Sometimes young believing men are tempted to think that God, by forbidding them to have sexual intercourse with their fiancée before marriage, does not pursue their good, but that’s not true; it is a lie, whose father is the devil. It cannot be true because God is love, God is good, God is right. They wilfully forget that it is God who made man and woman, and that He knows very well whether a thing is good for us or not. Young people, heed the Word of God and you will find good (Proverbs 19:8)!

However, fornication is also the sexual intercourse between a man and a prostitute; therefore we must flee any sexual intercourse with a prostitute. For Paul wrote to the Corinthians: “Now the body is not for fornication, but for the Lord; and the Lord for the body. And God hath both raised up the Lord, and will also raise up us by his own power. Know ye not that your bodies are the members of Christ? shall I then take the members of Christ, and make them the members of an harlot? God forbid [Certainly not!]. What? know ye not that he which is joined to an harlot is one body? for two, saith he, shall be one flesh” (1 Corinthians 6:13-16). Wisdom says that “a harlot is a deep pit” (Proverbs 23:27 – NKJV), and those who went to prostitutes before their conversion know how deep that pit is.

We, as believers in Christ Jesus, must always bear in mind that when we received Christ we became the temple of God, that is, we became members of Christ in that we became one spirit with Him, and let it be known to you that when the Scripture states that we are the temple of God it means that we are His house, as it is written: “And we are his house” (Hebrews 3:6 – NIV). Note that it is His house and not ours; therefore our members, having been bought at a price by Christ, do not belong to us any longer. We are His treasured possession, we don’t belong to ourselves; for this reason we can’t use our members to do whatever we like, because they are Christ’s. Fornicators sin against their own body, and therefore they profane the temple of God; that’s why the Scripture states that they will not inherit the kingdom of God (1 Corinthians 6:9).

Fornicators are punished by God as were those Israelites who committed fornication with the daughters of Moab (Numbers 25:1-9). Paul warns the saints against fornication, reminding them of that disobedience of the Israelites, when he says: “Neither let us commit fornication, as some of them committed, and fell in one day three and twenty thousand” (1 Corinthians 10:8).

We must not associate with anyone who calls himself a brother but is a fornicator, with such a man we must not even eat (1 Corinthians 5:9-11).
