D. L. Moody (1837-1899) made the following appeal in regard to the Sabbath:

"There has been an awful letting-down in this country regarding the Sabbath during the last twenty-five years, and many a man has been shorn of spiritual power, like Samson, because he is not straight on this question. Can you say that you observe the Sabbath properly? You may be a professed Christian: are you obeying this commandment? Or do you neglect the house of God on the Sabbath day, and spend your time drinking and carousing in places of vice and crime, showing contempt for God and His law? Are you ready to step into the scales? Where were you last Sabbath? How did you spend it?

I honestly believe that this commandment is just as binding today as it ever was. I have talked with men who have said that it has been abrogated, but they have never been able to point to any place in the Bible where God repealed it. When Christ was on earth, He did nothing to set it aside; He freed it from the traces under which the scribes and Pharisees had put it, and gave it its true place. 'The Sabbath was made for man, not man for the sabbath.'  It is just as practicable and as necessary for men today as it ever was-in fact, more than ever, because we live in such an intense age.

The Sabbath was binding in Eden, and it has been in force ever since. The fourth commandment begins with the word remember, showing that the Sabbath already existed when God wrote this law on the tables of stone at Sinai. How can men claim that this one commandment has been done away with when they will admit that the other nine are still binding?

I believe that the Sabbath question today is a vital one for the whole country. It is the burning question of the present time. If you give up the Sabbath the church goes; if you give up the church the home goes; and if the home goes the nation goes. That is the direction in which we are traveling.

The church of God is losing its power on account of so many people giving up the Sabbath, and using it to promote selfishness."
