Martyn Isles does a great job of showing us why Sunday, the first day of the week is the Lord’s Day for the church.

The “Lord’s Day” in Revelation 1:10 is not a vague reference to any day, but a day uniquely devoted to the risen Christ. Understanding why the early church honoured Sunday brings renewed clarity about worship, rest, and the serious spiritual purpose God has woven into the first day of the week.
