“For this is the will of God, even your sanctification, that ye should abstain from fornication: that every one of you should know how to possess his vessel in sanctification and honour; not in the lust of concupiscence, even as the Gentiles which know not God: that no man go beyond and defraud his brother in any matter: because that the Lord is the avenger of all such, as we also have forewarned you and testified.” 1 Thessalonians 4:3-6 (KJV)
The will of God is not something that we must find out through trial and error. It is not a mystery where we go around searching for it, wondering what God’s plan for our life is.
The apostle tells us above in the word of God, in the Letter of First Thessalonians we can see quite clearly that the will of God is for us to be “Sanctified”. Sanctification is a work of grace God gives us through Christ, where the Spirit of God in us directs us in God’s way, God’s will, God’s word, and leads us into holiness and right living.
For the people of Thessalonica there was much temptations around; as there are for Christians in 2016. The apostle was giving the people of that era instruction in sanctification of how to face the lustful, sensuous, immoral temptations.
“Everyone of you should know how to possess his vessel…” speaking of our bodies, and I certainly see reason to believe that this can refer to the fruit of the Spirit of God in Galations 5:22-23, and the fruit of “Temperance which is Self-control”.
It deals with treating our brethren rightly to in these matters – “…That no man go beyond and defraud his brother in any matter…”
It is the will of God that His people are being sanctified. In Jesus’s priestly prayer of John 17 He prays “Sanctify them through Your truth; Your word is truth.” (v. 17).
