I love this Q&A, especially the second part of the answer connecting the Sabbath command to our eternal rest and how we experience the eternal Sabbath of God even now. Wonderful.
Question #103: What is God's will for you in the fourth commandment?
Answer: First, that the gospel ministry and education for it be maintained, and that, especially on the festive day of rest, I regularly 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 already in this life the eternal Sabbath (Deut. 6:4-9, 20-25; 1 Cor. 9:13-14; 2 Tim. 2:2; 3:13-17; Tit. 1:5; Deut. 12:5-12; Ps. 40:9-10; 68:26; Acts 2:42-47; Heb. 10:23-25; Rom. 10:14-17; 1 Cor. 14:31-32; 1 Tim. 4:13; 1 Cor. 11:23-25; Col. 3:16; 1 Tim. 2:1; Ps. 50:14; 1 Cor. 16:2; 2 Cor. 8 & 9; Isa. 66:23; Heb. 4:9-11).
