Heb 7:27, Deut 8:3, Jn 6:32-33, 35, 48-51
In the Old Testament, the Israelites who left Egypt offered sacrifices to God every day. (Numbers 28:3-4)
Numbers 28:3 And thou shalt say unto them, This is the offering made by fire which ye shall offer unto the Lord; two lambs of the first year without spot day by day, for a continual burnt offering. 4 The one lamb shalt thou offer in the morning, and the other lamb shalt thou offer at even;
Jesus offered himself to God on the cross once for all, so we no longer have to offer daily sacrifices. (Heb 7:27)
Heb 7:27 Who needeth not daily, as those high priests, to offer up sacrifice, first for his own sins, and then for the people's: for this he did once, when he offered up himself.
We must live by the word of God every day. (Deut 8:3)
Deut 8:3 And he humbled thee, and suffered thee to hunger, and fed thee with manna, which thou knewest not, neither did thy fathers know; that he might make thee know that man doth not live by bread only, but by every word that proceedeth out of the mouth of the Lord doth man live.
Just as the Israelites offered daily sacrifices to God in the Old Testament, now we need Christ every day. (John 6:32-33,35,48-51)
John 6:32 Then Jesus said unto them, Verily, verily, I say unto you, Moses gave you not that bread from heaven; but my Father giveth you the true bread from heaven. 33 For the bread of God is he which cometh down from heaven, and giveth life unto the world. 35 And Jesus said unto them, I am the bread of life: he that cometh to me shall never hunger; and he that believeth on me shall never thirst. 48 I am that bread of life. 49 Your fathers did eat manna in the wilderness, and are dead. 50 This is the bread which cometh down from heaven, that a man may eat thereof, and not die. 51 I am the living bread which came down from heaven: if any man eat of this bread, he shall live for ever: and the bread that I will give is my flesh, which I will give for the life of the world.
