Many times, we wonder, “What is God’s will for me? ” Here, God tells us. It is His will that we be sanctified, meaning “made holy” or “set apart” from the filth and corruption that is in the world through lust. (2 Peter 1:4)

And one major area of sanctification Paul mentions, fornication, because it is so prevalent and so degrading.
And we pray:
Lord God, we do not always know what Your will is as to each path or decision of life. But we always know that Your will is for us to be holy even as You are holy. Sanctify us through Your Word, which is truth. (John 17:17) Keep us unspotted from the world in regard to sexual sin and all other sins. Amen.
I was taught as a young believer that no where in the Bible does God clearly say, “This is My will:” except for in the next chapter, when Paul writes, “In everything give thanks, for this is the will of God in Christ Jesus for you.” We can plainly see that this teaching is untrue, for not only does Paul expound in many places throughout the epistles, that it is will of God that we increase in sanctification, followed by examples of what such a sanctified life would look like (as in today’s reading), but Jesus also did not mince words about the matter. Nor, if anyone reads the Bible for themselves, does Moses, nor do the Psalms, the Proverbs, or the Prophets.
We can know the will of God. It begins with His general will for all mankind: do not worship idols, honor the Sabbath day to keep it holy, do not murder, do not steal, and so on as the Ten Commandments summarize. If someone were seeking the direction of God’s will for their life, start there! Learn the general will of God for all mankind and begin to implement it. The people who actually do this are relatively few and far between, and when someone sets their heart on obedience to God, believe me, it gets His attention.
Then as that person asks and keeps on asking for revelation of His specific and individual will for them, I think they would find God to not be slow in answering that prayer. Why does the process start with His general will? Because the one who is willing to start there, is willing to begin at the beginning of wisdom (Psa 111:10), and they open themselves up for greater and greater wisdom as they progress.
