What does Scripture say about this conundrum? The human body was made for periods of work interspersed with periods of rest. We are commanded by God to rest: “Remember the Sabbath and keep it holy. Six days you shall labor, and do all your work, but the seventh day is a Sabbath to the Lord your God.” (Ex. 20:8-10). Furthermore, the Lord made provision for a Sabbath year in which to rest for a whole year after six years of work (Lev. 25:3-7). The Lord would provide all the food needed for that seventh year even as the fields and trees grow wild for a year. And there is even a year of Jubilee (Lev. 25:8-22). The 50th year (after 7 Sabbath year cycles) would be an extra year of Sabbath rest for the land. No work would be done on the land. And God, who would plan for this, would make the sixth year (the one right before Sabbath and then Jubilee) so abundant that in one year, the Israelites would have enough food for all three years. God desires for us to rest from our labors and provides the means for us to take it.
Why does God want our rest? As God is holy, we are to be holy. As God rested, we are to rest (Ex.20:11). God is the one who sanctifies us and makes us holy, and one of the ways he does it is through rest, completely dedicating a day to him and no other pursuits (Ex. 13-14). This is important. It may not be enough to stop work, because we inevitably fill that time with other things. Dedicate that time to God alone, and he will bless you. Spend that time recharging spiritually. Furthermore, Israel was in slavery in Egypt and was forced into interminable, heavy labor (Ex. 1:13). God’s people will no longer be slaves to anyone, least of all to their own labors, but they will be servants to their God alone (Deut. 5:15). We do this so that we can be close with God and be holy like him.
What does that look like? Every day, every week, every year, set aside some time and spend that doing “nothing” - for the Lord. Spend it with your wife and children. Spend it reading Scripture. Spend it in prayer. When you take a vacation, go have fun and experience new things in life, but also spend it recharging your spirit. And unplug once in a while. I have never heard the Lord clearer than when I am away from business and electronics and the like. We were designed to rest in God. It’s what our bodies are supposed to do. I hope that you all will take some time to Sabbath in the Lord.
