It is good to rest on the Sabbath-day from the works of our calling; but if we rest from labour and do no more, the ox and the ass keep the Sabbath as well as we; for they rest from labour. We must dedicate the day to God; we must not only 'keep a Sabbath,' but 'sanctify' a Sabbath.Ten Commandments, 100
Sabbath rest is not the post-eschaton Sabbath celebrated in heaven, nor the rest that believers experience in death, but a present rest enjoyed by those who believe (4:3), anticipating a greater future "rest" (4:11). Human Sabbath keeping is a metaphor for cessation from works (4:10) in commemoration of God's rest at creation (4:4=Gen. 2:2) and of salvation provided by Christ. The physical Sabbath rest that God's people enjoy reflects the inner spiritual rest, which is a deposit of the final eschatological rest proleptically experienced "today" (4:7)For the Glory of God (280)
One day in seven should be especially devoted to corporate worship and other spiritual exercises that restore the soul's rest in God and zeal for His name. It should provide physical refreshment and fit one for a week of devoted service to Christ.https://www.desiringgod.org/articles/a-baptist-catechism
his grandfather's generation referred to Sunday as the 'holy Sabbath,' his father's to the 'Sabbath,' and his to 'Sunday.' Today we think of it as the back half of the 'weekend.' This may be the commandment most visibly ignored and overtly violated by professed Bible-believing Christians today.The Christian Sabbath, 5
It is sacrilege to rob for civil work the time which God has set apart for his worship. He that devotes any time of the Sabbath to worldly business, is a worse thief than he who robs on the highway; for the one does but rob man, but the other robs God.Ten Commandments, 99
