Sunday is commonly called the Sabbath by many denominations. This is a mistake. The Sabbath of the Bible was the day just preceding the first day of the week. The first day of the week is never called the Sabbath anywhere in the entire Scriptures.
Have you ever thought about what day God created the world? God created the world on the first day. That first day is what we call “Sunday.” (Gen 1:1-5) We know that this day was first, because the seventh day was the “Sabbath (from the Hebrew word for seven),” the day on which God rested, and “blessed the seventh day and sanctified it.” (Gen 2:1-3) The Sabbath was designated for rest from laborious work, “as a perpetual covenant” between God and His people (Israel). (Ex 31:12-17) The people were to rest when God had rested, but God worked on Sundays.
Jews met to worship God on the Sabbath, during that time of rest and reflection, and trust in God’s providence. (Nu 28:9-10 ff; Mk 1:21; Acts 13:14) Pursuing earthly needs keeps our focus on physical things, and there is a time to reflect on spiritual pursuits. Exercising our capacity derived from God’s grace is appropriate, but we must occasionally take time cease from our labors and rest in Him.
In the New Testament, Jesus made a distinction between the normal, laborious work of humans, and the service that He provided in teaching and healing. (Matt 12:5-6 f; Lk 14:1-6) He also explained that the Sabbath was a gift to the people, not a master to bow under in servitude. “The Sabbath was made for man, and not man for the Sabbath.” (Mk 2:27) However, this is not to say that Jesus did not keep the Sabbath according to God’s will while he was upon the earth. Even His time in the grave was significant, because in it, Jesus rested on the Sabbath (Lk 23:50-24:3). After all, the law of Moses was in effect up and until Jesus’ resurrection.
“The law and the prophets were until John: since that time the kingdom of God is preached, and every man presses into it. (Lk 16:16) The gospel was the death, burial, and resurrection of Jesus Christ. (1 Cor 15:1-4). Therefore, the gospel could not take effect until Jesus arose from the dead. Thus, on the day of Pentecost (7 Sabbaths + one day), which was always on a Sunday, the apostles began to preach the gospel and all who obeyed were added to the Lord’s church (Acts 2:37-47).
God’s plan resulted in Jesus being raised on the first day of the week. (Matt 28:1 ff; Mk 16:2; Lk 24:1; Jn 20:1) His disciples met on the first day of the week. (Mk 16:9 ff; Jn 20:19, 26) Saints meet on the day Jesus was raised to remember the Lord’s death by partaking of the Lord’s supper. (Acts 20:7 f; 1 Cor 11:24-26) Therefore, when we meet on Sunday, it’s the beginning of the week. This reminds us there’s work to do. In our culture, we talk about dreading the return of Monday, but the truth is, Monday is the second day of the week. Christians start work on Sunday. As for the Sabbath, it ended when the law of Moses ended. It ended when Jesus nailed it to his cross (Col 2:14).
Conclusion: Don’t make the mistake of treating Sunday as the Sabbath. The Sabbath was a day of rest to remember how God delivered Israel from the Egyptians, and Sunday is a day of work to remember how Jesus died for our sins. Therefore, beginning on Sunday, sing, preach, pray, give, and above all remember the Lord’s death by partaking of the Lord’s supper. And if you see someone in need on your journey to worship, help them. If you must work to support your family on this day you have not sinned. However, cease not to worship the Lord on Sunday, for that would be a sin (Heb 10:25).
