Q. What is God’s will for you in the fourth commandment [ie, “Remember the Sabbath day, to keep it holy”?
A. First, that the gospel ministry and education for it be maintained, and that, especially on the festive day of rest, I diligently attend the assembly of God’s people to learn what God’s Word teaches, to participate in the sacraments, to pray to God publicly, and to bring Christian offerings for the poor. Second, that every day of my life I rest from my evil ways, let the Lord work in me through his Spirit, and so begin in this life the eternal Sabbath.

“Day and night this was his secret, ‘just to roll the burden on the Lord.’ Frequently those who were wakeful in the little house at Chinkiang might hear, at two or three in the morning, the soft refrain of Mr. Taylor’s favorite hymn [‘Jesus, I am resting, resting, in the joy of what Thou art’]. He had learned that for him, only one life was possible—just that blessed life of resting and rejoicing in the Lord under all circumstances, while He dealt with the difficulties, inward and outward, great and small.’”
