Ephesians 6:22. “Whom I have sent unto you for the same purpose, that ye might know our affairs, and that he might comfort your hearts.”
Paul was in prison when he wrote the letter to the Ephesians. He didn’t know how much longer Rome would let him live, and he knew the people in all the churches he’d helped establish prayed for him and wanted news of him. It was for this reason that he sent men like Tychicus to take his letters to the churches. Not only would the messenger deliver the letter, which was usually read to the entire body; he would also bring news of Paul’s health, his legal status, and whether there was any hope that he would be able to visit them again.
As far as we know, this epistle was written in a.d. 64. Best estimates are that Paul died sometime in a.d. 65-68. He felt. toward his converts, as a loving father does toward his children. He considered the fears they would have for his well-being, That is why his benedictions are often so tender.
