Answer: Let everyone weigh the words of Christ and of Paul, referred to above, and he/she will discover whether it is a divine commandment or whether it is a counsel.
Everything which Paul says regarding separation he generally speaks in the imperative mode; that is, in a commanding manner.
Expurgo, that is, Purge, 1 Cor. 5:7. Profligo, that is, drive out. That is, withdraw from, 1 Tim. 6:5. Fuge, that is, flee, Tit. 3:9. Again, "We command you, brethren, in the name of our Lord Jesus Christ," 2 Thess. 3:6.
I think, brethren, these Scriptures show that it is a command. Even if it were not a command but advice of God, should we not diligently follow such advice?
If my spirit despises the counsel of the Holy Spirit, then I truly acknowledge that my spirit is not of God. As can be observed in numerous instances today, many Christians throughout history have not followed God's Spirit but their own.
