“ ‘I the Lord thy God am a jealous God.’ The close and sacred relation of God to His people is represented under the figure of marriage. Idolatry being spiritual adultery, the displeasure of God against it is fitly called jealousy.
“ ‘Visiting the iniquity of the fathers upon the children unto the third and fourth generation of them that hate Me.’ It is inevitable that children should suffer from the consequences of parental wrongdoing, but they are not punished for the parents’ guilt, except as they participate in their sins. It is usually the case, however, that children walk in the steps of their parents. By inheritance and example the sons become partakers of the father’s sin. Wrong tendencies, perverted appetites, and debased morals, as well as physical disease and degeneracy, are transmitted as a legacy from father to son, to the third and fourth generation. This fearful truth should have a solemn power to restrain men from following a course of sin.
“ ‘Showing mercy unto thousands of them that love Me, and keep My commandments.’ In prohibiting the worship of false gods, the second commandment by implication enjoins the worship of the true God. And to those who are faithful in His service, mercy is promised, not merely to the third and fourth generation as is the wrath threatened against those who hate Him, but to thousands of generations.
“ ‘Thou shalt not take the name of the Lord thy God in vain: for the Lord will not hold him guiltless that taketh His name in vain.’
“This commandment not only prohibits false oaths and common swearing, but it forbids us to use the name of God in a light or careless manner, without regard to its awful significance. By the thoughtless mention of God in common conversation, by appeals to Him in trivial matters, and by the frequent and thoughtless repetition of His name, we dishonor Him. ‘Holy and reverend is His name.’ Psalm 111:9. All should meditate upon His majesty, His purity and holiness, that the heart may be impressed with a sense of His exalted character; and His holy name should be uttered with reverence and solemnity.
“ ‘Remember the Sabbath day, to keep it holy. Six days shalt thou labor, and do all thy work: but the seventh day is the Sabbath of the Lord thy God: in it thou shalt not do any work, thou, nor thy son, nor thy daughter, thy manservant, nor thy maidservant, nor thy cattle, nor thy stranger that is within thy gates: for in six days the Lord made heaven and earth, the sea, and all that in them is, and rested the seventh day: wherefore the Lord blessed the Sabbath day, and hallowed it.’
“The Sabbath is not introduced as a new institution but as having been founded at creation. It is to be remembered and observed as the memorial of the Creator’s work. Pointing to God as the Maker of the heavens and the earth, it distinguishes the true God from all false gods. All who keep the seventh day signify by this act that they are worshipers of Jehovah. Thus the Sabbath is the sign of man’s allegiance to God as long as there are any upon the earth to serve Him. The fourth commandment is the only one of all the ten in which are found both the name and the title of the Lawgiver. It is the only one that shows by whose authority the law is given. Thus it contains the seal of God, affixed to His law as evidence of its authenticity and binding force.”
