I am sharing the following with you, friend, with the hope that it will be of help to you. I need assistance from the Lord, as well, in doing right in His sight. It is for sure, I do not have my act together as well as I should. I think of what the Apostle Paul said: “But I keep under my body, and bring it into subjection: lest that by any means, when I have preached to others, I myself should be a castaway.” I Corinthians 9:27
“Remember the sabbath day, to keep it holy. Six days shalt thou labour, 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.” Exodus 20:8-11
…You must have higher views of God’s claims upon you in regard to His holy day. Everything that can possibly be done on the six days which God has given to you, should be done. You should not rob God of one hour of holy time. Great blessings are promised to those who place a high estimate upon the Sabbath and realize the obligations resting upon them in regard to its observance: “If thou turn away they foot from the Sabbath (from trampling upon it, setting it at nought), from doing they pleasure on My holy day; and call the Sabbath a delight, the holy of the Lord, honor able; 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.” Isaiah 58:13, 14
When the Sabbath commences, we should place a guard upon ourselves, upon our acts and our words, lest we rob God by appropriating to our own use that time which is strictly the Lord’s. We should not do ourselves, nor suffer our children to do, any manner of our own work for a livelihood, or anything which could have been done on the six working days. Friday is the day of preparation. Time can then be devoted to making the necessary preparation for the Sabbath and to thinking and conversing about it. Nothing which will in the sight of Heaven be regarded as a violation of the holy Sabbath should be left unsaid or undone, to be said or done upon the Sabbath. God requires not only that we refrain from physical labor upon the Sabbath, but that the mind be disciplined to dwell upon sacred themes. The fourth commandment is virtually transgressed by conversing upon worldly things or by engaging in light and trifling conversation. Talking upon anything or everything which may come into the mind is speaking our own words. Every deviation from right brings us into bondage and condemnation.
…Those who are not fully converted to the truth frequently let their minds run freely upon worldly business, and, although they may rest from physical toil upon the Sabbath, their tongues speak out what is in their minds; hence these words concerning cattle, crops, losses, gains. All this is Sabbath breaking. If the mind is running upon worldly matters, the tongue will reveal it; for out of the abundance of the heart the mouth speaketh.
…Of all days in the week, none are so favorable for devotional thoughts and feelings as the Sabbath.
All heaven was represented to me as beholding and watching upon the Sabbath those who acknowledge the claims of the fourth commandment and are observing the Sabbath. Angels were marking their interest in, and high regard for, this divine institution. Those who sanctified the Lord God in their hearts by a strictly devotional frame of mind, and who sought to improve the sacred hours in keeping the Sabbath to the best of their ability, and to honor God by calling the Sabbath a delight–these the angels were specially blessing with light and health, and special strength was given them. But, on the other hand, the angels were turning from those who failed to appreciate the sacredness of God’s sanctified day, and were removing from them their light and their strength. I saw them overshadowed with a cloud, desponding, and frequently sad. They felt a lack of the Spirit of God.
