What does Ephesians 6:22 mean?

This verse clearly expresses the reasons Paul sent Tychicus to Ephesus with this letter: "I have sent him to you for this very purpose." Two reasons are given. First, "that you may know how we are." The "we" in this verse may also refer to the others serving with Paul in Rome during this time. These included Aristarchus, Mark, Jesus called Justus, Epaphras, Luke, and Demas (Colossians 4:10–14).

Second, Paul sent Tychicus to "encourage your hearts." Tychicus was likely gifted as an encourager. Paul wanted him to build up the Ephesian believers with encouraging stories and teachings in addition to those shared in Paul's written letter. Tychicus is also noted as a person who would encourage the hearts of the Colossian believers (Colossians 4:8). Though not the top leader, Tychicus served as an important figure and had tremendous influence in the early church, traveling to several locations both with Paul and apart from him to share the gospel and encourage early believers.
