After the sin enter the world, the Death started to rule over the human race.
This means that the genes of the human race were damaged, deformed, malfunctioned, disabled, that some people were born as blind, deaf, dumb, diabetes sensitive, with obesity genes, stroke genes, many weakness of stomach. liver, hair loss, fertility problem, depression, innate heart disease, irregular teeth, dental weakness, thyroid hormone problem, various alergy such as peanut alergy, aphasia, autism, etc., and thousand more diseases and weaknesses.
I am very sure that nobody was born without any defects.
On the other hand the OT teaches us the shadow of Jesus Christ like this:
I hope many of you know that Red Heifer is the exact Type of Jesus Christ, the Sinless and Blemish Sacrifice.
Numbers 19:
2This is the ordinance of the law which the LORD hath commanded, saying, Speak unto the children of Israel, that they bring thee a red heifer without spot, wherein is no blemish, and upon which never came yoke:
3And ye shall give her unto Eleazar the priest, that he may bring her forth without the camp, and one shall slay her before his face:
4And Eleazar the priest shall take of her blood with his finger, and sprinkle of her blood directly before the tabernacle of the congregation seven times:
5And one shall burn the heifer in his sight; her skin, and her flesh, and her blood, with her dung, shall he burn:
6And the priest shall take cedar wood, and hyssop, and scarlet, and cast it into the midst of the burning of the heifer. 7Then the priest shall wash his clothes, and he shall bathe his flesh in water, and afterward he shall come into the camp, and the priest shall be unclean until the even.
9And a man that is clean shall gather up the ashes of the heifer, and lay them up without the camp in a clean place, and it shall be kept for the congregation of the children of Israel for a water of separation: it is a purification for sin.
10And he that gathereth the ashes of the heifer shall wash his clothes, and be unclean until the even: and it shall be unto the children of Israel, and unto the stranger that sojourneth among them, for a statute for ever.
18And a clean person shall take hyssop, and dip it in the water, and sprinkle it upon the tent, and upon all the vessels, and upon the persons that were there, and upon him that touched a bone, or one slain, or one dead, or a grave:
Red Heifer was selected by the priests and they examined if they had any black whiskers, they were disqualified. If they had any scars due to the fighting with other cows, they were disqualified. The Heifer must have been perfect in many aspects.
Why?
Because the Red Heifer represented the sinless person, Jesus Christ.
If Jesus took the ovum of Mary, the innate sinner, then could He be perfect and blemish?
As the sinners were forgiven and became clean by being sprinkled with the Ash Water of the Red Heifer, we are daily cleansed from our sins due to what Jesus did at the Cross.
Could Ovum of Mary be perfect as the Blemish, Spotless, Red Heifer?
