There are a few key things you should know about Sabbath vs Sunday, the Bible versus Tradition, and God's will for your life vs human opinion.
God never suggested, requested, invited, commanded or promised blessings for worshiping on Sunday. There is no command to worship on Sunday. There is no blessing promised for doing so. God never gives the day any form of designation or title. The idea of worshiping on Sunday, substituting it for Sabbath, is completely absent from scripture.
The New Testament records a huge debate about circumcision, but never even hints at a departure from Sabbath-keeping. There is no record of any New Testament observance of Sunday as Sabbath; nor of worship on Sunday instead of on Sabbath. In fact, Sunday is clearly identified as a day for book-keeping (1 Corinthians 16:2).
Given the idea is absent from scripture, why do most Christians worship on Sunday today? It is clear they do so because of tradition. Tradition that comes from man, not from God. In looking back to the origin of Christian worship on Sunday, it is apparent that the pagan worship of light and sun (and a healthy dose of anti-semitism) factored heavily into the man-made move to substitute Sunday for Sabbath.
God instituted Sabbath at creation for the benefit of mankind. He rested on the seventh day for an example. He also blessed and consecrated it, that we may experience divine blessing through imitating His example. The Sabbath summons mankind to imitate the pattern of the King, and so to confess God's lordship.
Genesis 2:2, 3; Mark 2:27; Exodus 20:10; Isaiah 56:6; Isaiah 58:13–14
God commands people observe the Sabbath, and promises a blessing for its observance. Sabbath is on-going and current in the New Testament, being mentioned over 50 times, with over 80 weekly sabbaths being referred to. The early church kept the Sabbath, and assumed that its observance would continue indefinitely. Sabbath observance is God's on-going will for us.
Exodus 20:8–11; Deuteronomy 6:12–15; Isaiah 58:14; Luke 4:16; Acts 17:2; Acts 18:4, 11; Acts 15:21; Hebrews 4:9
Seventh Day Baptists and Sabbath
Seventh Day Baptists enter into God's sabbath rest each Sabbath. In doing so, we are responding to God's gracious invitation to set aside 24 hours a week to dwell with Him, undistracted by the hustle and bustle of life.
When God created the world, He rested with Adam and Eve on the seventh day. At Sinai, he reminded his covenant people to enter into his Sabbath rest. Isaiah reminds us that this call to enter God's sabbath rest extends to people from every nation (Isaiah 56). And the book of Hebrews reminds us that "there remains a Sabbath rest for the people of God" (Hebrews 4:9).
We willingly accept God's call to dwell with Him in His holy time. We invite you to join us.
