NOTE.—If the Sabbath is to be kept “holy,” mere physical rest one day in seven cannot be the great object of the Sabbath institution. 11. How does the Lord, through the prophet Isaiah, indicate what is true Sabbath-keeping? “If thou _turn away thy foot from the Sabbath_, from doing _thy pleasure_ on My holy day; and _call the Sabbath a delight, the holy of the Lord, honorable_; and shalt _honor Him, not doing thine own ways, nor finding thine own pleasure, nor speaking thine own words_: then shalt thou _delight thyself in the Lord_; and I will cause thee to ride upon the high places of the earth, and feed thee with the heritage of Jacob thy father: for the mouth of the Lord hath spoken it.” Isa. 58:13, 14. NOTE.—“Whether the Sabbath becomes a delight or a burden depends upon the spirit with which a man meets it. Indeed, the spirit of the man settles the question as to the benefits to come from any duty he may perform. One man cannot understand why his neighbor should prefer the park or the ball ground to the church, simply because his spirit is different. He has cultivated the higher nature until he loves spiritual things above all others, and to him the Sabbath is indeed a delight. It comes to his weary soul as a reminder of God, and brings him nearer to heaven in heart and mind than does any other day.”—_Sabbath Recorder, Dec. 12, 1910._ 12. What is the character of God, and how only can He be truly worshiped? “_God is a Spirit_: and they that worship Him must worship Him _in spirit and in truth_.” John 4:24. NOTE.—This is one reason why the attempt to produce Sabbath-keeping by human Sabbath laws is altogether out of place. Such laws can never produce true Sabbath-keeping, for that is _spiritual_, and must be of the _mind_ and from the _heart_, and not _perfunctory_, _mechanical_, nor of _force_. 13. What is one thing for which God has given the Sabbath to be a sign? That He _sanctifies_ His people, or makes them _holy_. See Ex. 31:13; Eze. 20:12; and page 420. 14. What does the “psalm for the Sabbath day” suggest as proper acts and themes for thought and meditation on the Sabbath? “It is a good thing to _give thanks unto the Lord_, and to _sing praises unto Thy name, O Most High_: to show forth _Thy loving-kindness_ in the morning, and _Thy faithfulness_ every night, _upon an instrument of ten strings_, and upon the _psaltery_; upon the _harp_ with a solemn sound. For Thou, Lord, hast made me glad _through Thy work_: I will triumph in _the works of Thy hands_. O Lord, _how great are Thy works_! and _Thy thoughts are very deep_.” Ps. 92:1-5. 15. What do the works of God declare? “The heavens declare _the glory of God_; and the firmament showeth _His handiwork_. Day unto day uttereth _speech_, and night unto night _showeth knowledge_. There is no speech nor language, where _their voice_ is not heard.” Ps. 19:1-3. See margin.
