“This is the will of God,
Your sanctification.
You must abstain
From fornication.”
Τοῦτο γάρ ἐστιν θέλημα τοῦ Θεοῦ, ὁ ἁγιασμὸς ὑμῶν, ἀπέχεσθαι ὑμᾶς ἀπὸ τῆς πορνείας,
Paul said, “This is the will of God (Τοῦτο γάρ ἐστιν θέλημα τοῦ Θεοῦ), your sanctification (ὁ ἁγιασμὸς ὑμῶν). You must abstain (ἀπέχεσθαι ὑμᾶς) from fornication (ἀπὸ τῆς πορνείας).” Only the Pauline letters used this word ἁγιασμὸς, that means consecration, sanctification, becoming holy, set apart, or consecrated. Paul explained that to follow Jesus Christ they had to do the will of God. They had to be sanctified or consecrated as holy to God. This commandment of holiness meant that they were to abstain from fornication, any kind of sexual immorality. Remember that this was the main thing that they asked for converts from the gentile pagan Greek culture, monotheism and abstaining from immoral sexual conduct. Do you abstain from immoral sexual conduct?
