“But now you yourselves are to put off all these: anger, wrath, malice, blasphemy, filthy language out of your mouth.”
We come to the fifth garment we are to put off like a dirty garment. God demands that our lips be a credit to Christ. He does not want us to bring reproach to the name of Christ. This is a reasonable expectation on God’s part. God made an enormous investment in us by giving his Son on the cross. He has given us the permanent indwelling of the Holy Spirit and the Word of God. With all this spiritual equipment, he has a right to expect more of us than we are giving him.
Filthy language is foul talk, including crude and coarse language.
Many Christians revert to filthy language when frustrated. They become obscene because they do not handle their problems biblically.
