Colossians 4 is a chapter that highlights various instructions and greetings from the apostle Paul to the believers in Colossae. Paul urges the believers to walk in wisdom toward those outside the faith, making the most of their interactions and conversations. He encourages them to let their speech always be gracious, seasoned with salt, so that they may know how to answer everyone. Paul also sends greetings to several individuals, including Tychicus, Onesimus, Aristarchus, Mark, and others, acknowledging their support and partnership in the ministry. He advises the Colossians to receive Mark warmly if he visits them, showing forgiveness and reconciliation. Paul mentions Epaphras, a fellow servant who has been laboring fervently for the believers in Colossae, and sends his greetings. He concludes the letter by urging the believers to exchange greetings with the Laodiceans and to read this letter among themselves.
