The Sabbath is the Lord’s day, set apart each week for rest and worship.
In Old Testament times, God’s covenant people observed the Sabbath on the seventh day of the week because God rested on the seventh day when He had created the earth (see Genesis 2:2). After the Resurrection of Jesus Christ, which occurred on the first day of the week (see Mark 16:2), the Lord’s disciples began observing the Sabbath on the first day of the week, Sunday (see Acts 20:7).
The Lord emphasized the importance of Sabbath observance in the Ten Commandments when He said, “Remember the sabbath day, to keep it holy” (see Exodus 20:8–11). The Savior Himself kept the Sabbath day holy during his mortal life (see Matthew 12:9–13; Luke 4:16; John 5:9) The Lord told Moses that Sabbath observance was a sign of the covenant between Him and His people and that if they would keep it holy they would know Him as their Lord and God (see Exodus 31:13; see also Ezekiel 20:20).
