If we seek to be innovative about how we run our lives. If we seek to hear Jesus better, know Jesus better, obey Jesus better, we need to try as much as possible to rest one day a week.
The focus of our rest should not be on church service though. Church service is a means to an end. The focus of our rest should be on celebration of the spiritual rest (salvation, reconciliation) that we already have in Jesus Christ. When we focus on celebrating the spiritual rest we have in Christ, we receive rest for our bodies even if we do not actually take time to rest physically in the sense of getting some sleep.
Is this scriptural? Paul declares in Romans 8:11 (NIV) :
And if the Spirit of Him who raised Jesus from the dead is living in you, He who raised Christ from the dead will also give life to your mortal bodies through His Spirit; who lives in you.
There was a period of my life during which I did not keep Sabbath though I was in a position to do so. During this period, I was under no obligation to an employer to work 7 days a week. Now that I have rediscovered the Sabbath principle, I realize there was calm and spiritual life I could have had access to that I did not take advantage of because I felt I could not afford to abstract away from what I did for a living for even one day.
I encourage you to make the Sabbath principle part of your weekly life, with focus not on participating in church service necessarily but on celebration of the spiritual rest you already have in Jesus Christ. Celebration of our earthly relationships is a part of this celebration, which is where attendance at church services comes into the picture. If attendance at church service begins, however, to militate against the rest we celebrate, like Paul we abandon the traditional places of fellowship —in Paul’s time this was the synagogue — and seek out other platforms for interaction with fellow Christians.
I note here that some Christians spend so much time with other Christians on Sabbath they actually do not get to spend any time with their spouses or children on Sabbath. Unless a believer is a pastor, in which case he or she has Monday through Friday to catch up with his or her family, this is abuse of Sabbath. I speak not because I never have been guilty of this type of abuse, but because I have received enlightenment of the Holy Spirit on these matters.
Ours indeed is a great and common salvation.
