7 ‘But if [e]he cannot afford a lamb, then he shall bring to the Lord his guilt offering for that in which he has sinned, two turtledoves or two young pigeons, one for a sin offering and the other for a burnt offering. 8 He shall bring them to the priest, who shall offer first that which is for the sin offering and shall nip its head at the front of its neck, but he shall not sever it. 9 He shall also sprinkle some of the blood of the sin offering on the side of the altar, while the rest of the blood shall be drained out at the base of the altar: it is a sin offering. 10 The second he shall then prepare as a burnt offering according to the ordinance. So the priest shall make atonement on his behalf for his sin which he has [f]committed, and it will be forgiven him.
11 ‘But if his [g]means are insufficient for two turtledoves or two young pigeons, then for his offering for that which he has sinned, he shall bring the tenth of an [h]ephah of fine flour for a sin offering; he shall not put oil on it or place incense on it, for it is a sin offering. 12 He shall bring it to the priest, and the priest shall take his handful of it as its memorial portion and offer it up in smoke on the altar, [i]with the offerings of the Lord by fire: it is a sin offering. 13 So the priest shall make atonement for him concerning his sin which he has [j]committed from one of these, and it will be forgiven him; then the rest shall become the priest’s, like the grain offering.’”
God didn’t want excuses when it came to His people restoring relationship with Him. He expected everyone to do their duty, and whatever was necessary to be forgiven of their sins. By the same token, He didn’t want the sacrifice to become a barrier that would be difficult to fulfill, so He made special rules for the poor so that they would never be excluded from His presence. By the same token, Jesus didn’t come just to save a specific group of people. God sent His Son to save the whole world from their sins, that we might all be reconciled to Him. He puts us all on a level playing field. He died for each of us, because He loves every single one of us.
