God’s memorial, the seventh-day Sabbath, the sign of His work in creating the world, has been displaced by the man of sin. God’s people have a special work to do in repairing the breach that has been made in His law; and the nearer we approach the end, the more urgent this work becomes. All who love God will show that they bear His sign by keeping His commandments. They are the restorers of paths to dwell in. . . . Genuine medical missionary work is bound up inseparably with the keeping of God’s commandments, of which the Sabbath is especially mentioned, since it is the great memorial of God’s creative work. Its observance is bound up with the work of restoring the moral image of God in man. This is the ministry which God’s people are to carry forward at this time. This ministry, rightly performed, will bring rich blessings to the church.
