“Thy name, O Lord, endureth forever; and _Thy memorial, O Lord; throughout all generations_.” Ps. 135:13. _Memorial_: “Anything intended to preserve the memory of a person or event; something which serves to keep some person or thing in remembrance, as a monument or a practise.”—_Webster._ 2. What illustration of this is given in the Bible? “And _these stones shall be for a memorial_ unto the children of Israel forever.” Joshua 4:7. 3. What were these stones to commemorate? “And he spake unto the children of Israel, saying, When your children shall ask their fathers in time to come, saying, What mean these stones? then _ye shall let your children know, saying, Israel came over this Jordan on dry land_.” Verses 21, 22. NOTE.—These stones were to be a standing memorial, or reminder, of Israel’s coming dry-shod over the Jordan. 4. What was another memorial instituted to commemorate another signal providence in behalf of the Israelites? “And _this day shall be unto you for a memorial_; and ye shall keep it a feast to the Lord throughout your generations; ye shall keep it a feast by an ordinance forever.” Ex. 12:14. NOTE.—This, the Passover, was a _periodical_ memorial, to be observed on the fourteenth day of the first month of each year, the day on which the Israelites were delivered from Egyptian bondage, and its celebration was to be, with the seven days’ feast of unleavened bread following and connected with it, in commemoration of that event. See Ex. 13:3-9. 5. Does God design that His great work of creating the heavens and the earth shall be remembered? “The works of the Lord are great, sought out of all them that have pleasure therein. His work is honorable and glorious: and His righteousness endureth forever. _He hath made His wonderful works to be remembered._” Ps. 111:2-4. 6. What has He commanded men to observe in memory of this great work? “_Remember the Sabbath day, to keep it holy_; ... 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.” Ex. 20:8-11. 7. Of what was this memorial to be a sign? “And hallow My Sabbaths; and they shall be _a sign_ between Me and you, _that ye may know that I am the Lord your God_.” Eze. 20:20. 8. How long was the Sabbath to be a sign of the true God? “_It is a sign between Me and the children of Israel forever_: for in six days the Lord made heaven and earth, and on the seventh day He rested, and was refreshed.” Ex. 31:17. NOTE.—It is manifest that if the object of the Sabbath was to keep God as the Creator in mind, and it had been faithfully kept from the first, there would not now be a heathen or an idolater on the face of the earth. 9. What besides creation were Israel to remember when they kept the Sabbath?
