Use one. See here the Christian’s duty, “to keep the Sabbath-day holy.”

(1) The whole Sabbath is to be dedicated to God. It is not said, Keep a part of the Sabbath holy but the whole day must be piously observed. If God has given us six days, and taken but one to himself, shall we grudge him any part of that day? This would be sacrilege. … Let those who say, that to keep a whole Sabbath is too Judaical, show where God has made any abatement of the time of worship; where he has said, you shall keep but a part of the Sabbath; and if they cannot show that, it robs God of his due. That a whole day be designed and set apart for his special worship, is a perpetual statute, while the church remains upon the earth, …

(2) As the whole Sabbath is to be dedicated to God, so it must be kept holy. …

“If you turn away your foot from the Sabbath, from doing your pleasure on my holy day; and call the Sabbath a delight, the holy of the Lord, honorable: and shall honor him, not doing your own ways, nor finding your own pleasure, nor speaking your own words.” Isaiah 58:13. Here is a description of rightly sanctifying a Sabbath.

“If you turn away your foot from the Sabbath.” This may be understood either literally or spiritually. Literally, that is, if you withdraw your foot from taking long walks or journeys on the Sabbath-day. So the Jewish doctors expound it. Or, spiritually, if you turn away your affections (the feet of your soul) from inclining to any worldly business.

“From doing your pleasure on my holy day.” That is, you must not do that which may please the carnal part, as in sports and recreations. This is to do the devil’s work on God’s day.

“And call the Sabbath a delight.” Call it a delight, that is, esteem it so. Though the Sabbath is not a day for carnal pleasure, yet holy pleasure is not forbidden. The soul must take pleasure in the duties of a Sabbath…

“Not doing your own ways.” That is, you shall not defile the day by doing any servile work.

“Nor finding your own pleasure.” That is, not gratifying the fleshly part by walks, visits, or recreations.

“Nor speaking your own words.” That is, words unsuitable for a Sabbath; vain, impertinent words; discourses of worldly affairs.

But not only must the new nature be fed, it is equally necessary for our spiritual well-being that the old nature should be starved. This is what the apostle had in mind when he said, “Make not provision for the flesh, unto the lusts thereof” (Rom. 13:14). To starve the old nature, to make not provision for the flesh, means that we abstain from everything that would stimulate our carnality; that we avoid, as we would a plague, all that is calculated to prove injurious to our spiritual welfare.

Not only must we deny ourselves the pleasures of sin, shun such things as the saloon, theatre, dance, card-table, etc., but we must separate ourselves from the worldly companions, cease to read worldly literature, abstain from everything upon which we cannot ask God’s blessing.

Our affections are to be set upon things above, and not upon things upon the earth (Col. 3:2).

Does this seem a high standard, and sound impracticable? Holiness in all things is that at which we are to aim, and failure to do so explains the leanness of so many Christians. Let the young believer realize that whatever does not help his spiritual life hinders it.

I must honestly declare my conviction that, since the days of the Reformation, there never has been so much profession of religion without practice, so much talking about God without walking with Him, so much hearing God’s words without doing them, as there is in England at this present date. Never were there so many empty tubs and tinkling cymbals! Never was there so much formality and so little reality. The whole tone of men’s minds on what constitutes practical Christianity seems lowered. The old golden standard of the behaviour which becomes a Christian man or woman appears debased and degenerated.

You may see scores of religious people (so-called) continually doing things which in days gone by would have been thought utterly inconsistent with vital religion. They see no harm in such things as card-playing, theatre-going, dancing, incessant novel-reading, and Sunday-travelling, and they cannot in the least understand what you mean by objecting to them! The ancient tenderness of conscience about such things seems dying away and becoming extinct, like the dodo. When you venture to remonstrate with young communicants who indulge in them, they only stare at you as an old-fashioned, narrow-minded, fossilized person and say, “Where is the harm?” In short, laxity of ideas among young men, and “fastness” and levity among young women, are only too common characteristics of the rising generation of Christian professors.

Now in saying all this I would not be mistaken. I disclaim the slightest wish to recommend an ascetic religion. Monasteries, nunneries, complete retirement from the world, and refusal to do our duty in it, all these I hold to be unscriptural and mischievous nostrums. Nor can I ever see my way clear to urging on men an ideal standard of perfection for which I find no warrant in God’s Word, a standard which is unattainable in this life, and hands over the management of the affairs of society to the devil and the wicked. No; I always wish to promote a genial, cheerful, manly religion, such as men may carry everywhere and yet glorify Christ.

John 17:16 – “They are not of the world, even as I am not of the world.”

2. Observe again, an excellent means to digest the world’s neglect is to consider the example of Christ. It is our duty, it will be for our comfort, and it turneth to our profit.

Prov 30:7-9 – “7 Two things have I required of thee; deny me them not before I die: 8 Remove far from me vanity and lies: give me neither poverty nor riches; feed me with food convenient for me: 9 Lest I be full, and deny thee, and say, Who is the Lord? or lest I be poor, and steal, and take the name of my God in vain.”

Lest I should steal, and take the name of my God in vain, that is, discredit my profession of religion by practices disagreeable to it.

Exo 20:7 – “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.”

[2] We take God’s name in vain, when we profess God’s name but do not live answerably to it, we take it in vain. They profess that they know God, but in works they deny him, Titus 1:16. When men’s tongues and lives are contrary to one another, when, under a mask of profession, they lie and deceive, and are unclean, they make use of God’s name to abuse him, and take it in vain. “Pretended holiness is merely double wickedness.” “The name of God is blasphemed among the Gentiles because of you.”, Rom 2:24. When the heathen saw the Jews, who professed to be God’s people, to be scandalous, it made them speak evil of God, and hate the true religion for their sakes.

[4] We take God’s name in vain, when we worship him with our lips but not with our hearts. God calls for the heart, “My son, give me your heart.”, Prov 23:26. The heart is the chief thing in religion; it draws the will and affections after it, as the Primum Mobile [the outermost moving sphere that carried the others with it in the geocentric view of the universe] draw the other orbs along with it. The heart is the incense which perfumes our holy things. The heart is the altar which sanctifies the offering. When we seem to worship God but withdraw our heart from him, we take his name in vain. “These people honor me with their lips, but their hearts are far from me. They worship me in vain.”, Matthew 15:8-9

Hypocrites take God’s name in vain: their religion is a lie; they seem to honor God but they do not love him; their hearts go after their lusts [generally, any corrupt desires of the heart]. “They set their heart on their iniquity.”, Hos 4:8. Their eyes are lifted up to heaven but their hearts are rooted in the earth, Ezek 33:31. These are devils in Samuel’s mantle.

Superstitious people take God’s name in vain. They bring him a few ceremonies which he never appointed, bow at Christ’s name and cringe to the altar but hate and persecute God’s image.
