Immediately after promising to be a Father to those who separate, God continues:
"Therefore, having these promises, beloved, let us cleanse ourselves from all filthiness of the flesh and spirit, perfecting holiness in the fear of God." 2 Corinthians 7:1
If you want to know God's will for your life RIGHT NOW, you have to cleanse yourself both inwardly and outwardly of filth. We have already seen that true separation does not mean obeying man-made rules while tolerating sin. True separation means getting rid of ALL filthiness of the flesh and spirit.
Okay, but what specific things is God talking about? God lists "the works of the flesh" in Galatians 5:19-21, telling us that "...the works of the flesh are evident, which are: adultery, fornication, uncleanness, lewdness,
20 idolatry, sorcery, hatred, contentions, jealousies, outbursts of wrath, selfish ambitions, dissensions, heresies,
21 envy, murders, drunkenness, revelries, and the like;"
If you want the guidance that God gives to separated Christians, God has given you a list to start off with.
