The New Testament Church practices the Lord’s Day on Sunday (Rev 1:9, Acts 20:7). The switch to Sunday was because of the resurrection of the Lord Jesus and the presence of his kingdom and new creation. The Saturday Sabbath is obsolete (Col 2:16) yet there still remains a Sabbath rest for the people of God to enter in the future (Heb 4:9), so the Lord’s day still points to the return of Christ and calls to faith, and the institution of the one holy day in seven continues. We still practice because we still need to enter the “rest” by faith (Heb 4:1-10). It is a moral duty for the Christian to worship the Lord on his day, but it, like all of the law, is freedom and blessing when kept with a love for Christ.
“I don’t Get it” Minute
The Lord’s Day: Christians worship on the Lord’s Day, that is Sunday. The reason for this is because since the creation of the world God called man to worship him in the pattern of one day out of seven (Gen 2:1-4). This pattern was also made more special for Israel with several feast days. The day is “holy” to the Lord, which means that it is devoted to his service (Exo 20:11, 23:12, Deut 5:15). The rest of the days of the week we work and labor under the sun, but during the Lord’s Day we rest in the hope and joy of the present new creation and salvation in Jesus.
Why celebrate the Lord’s Day? It is a day of special blessing. God attached promises to the day. In Isaiah 58:13-14 the prophet called Israel to keep the Sabbath because they were losing out on the blessing and delight of the Lord and his people. We also learn to rest and trust in Christ and his finished work on our behalf on the Lord’s Day. The cares of this world take a backseat to the Lord and his work and the promise of eternal life (Heb 4:10).
