Verily, this is fasting and prayer, or in other words, rejoicing and prayer. There is much more said in relation to this subject, but this will suffice for our purpose. Here the Lord speaks emphatically, but kindly. There must be great blessings awaiting those who have faith and integrity enough to obey this counsel. The Lord has never given a commandment to the members of the Church, or to the world, except it has been given for the everlasting welfare and blessing for all who obey it.
Every commandment given has to do with spiritual things.
The Lord declared that never at any time has he given unto man a law which is temporal in its nature. Although we fail to see it, every commandment has a spiritual application. This is definitely so in relation to the observance of the Sabbath day. It is very natural for children to ask why they should obey the law of the Sabbath as the Lord has proclaimed it. They are indeed worthy of an answer.
