Disagreements over Sabbath-keeping should not rupture the fellowship of believers, and the doctrine of the Sabbath does not share the importance of the doctrine of justification or the authority of Scripture. Yet neither do the Scriptures treat the Sabbath as a peripheral issue. Can we honestly say that the modern church has attached the same importance to Sabbath-keeping that God has? Whatever position you adopt with respect to Sabbath-keeping, may the weight the Word of God attaches to this subject drive you to study these things with greater urgency and with increased earnestness to understand the will of the Lord.
