The ministration of the sanctuary consisted of two divisions, a daily and a yearly service. The daily service was performed at the altar of burnt offering in the court of the tabernacle, and in the holy place; while the yearly service was in the most holy....
The daily service consisted of the morning and evening burnt offering, the offering of sweet incense on the golden altar, and the special offerings for individual sins. And there were also offerings for sabbaths, new moons, and special feasts.
Every morning and evening a lamb of a year old was burned upon the altar, with its appropriate meat offering, thus symbolizing the daily consecration of the nation to Jehovah, and their constant dependence upon the atoning blood of Christ. God expressly directed that every offering presented for the service of the sanctuary should be “without blemish. ”... Only an offering “without blemish” could be a symbol of His perfect purity who was to offer Himself as “a lamb without blemish and without spot.” 1 Peter 1:19. The apostle Paul points to these sacrifices as an illustration of what the followers of Christ are to become. He says, “I beseech you therefore, brethren, by the mercies of God, that ye present your bodies a living sacrifice, holy, acceptable unto God, which is your reasonable service.” ...
The hours appointed for the morning and the evening sacrifice were regarded as sacred, and they came to be observed as the set time for worship throughout the Jewish nation.... In this custom, Christians have an example for morning and evening prayer. While God condemns a mere round of ceremonies, without the spirit of worship, He looks with great pleasure upon those who love Him, bowing morning and evening to seek pardon for sins committed, and to present their requests for needed blessings.

Our circumstances and surroundings, the changes daily transpiring around us, and the written word of God which discerns and proves all things—these are sufficient to teach us our duty and just what we ought to do, day by day. Pr 160
