spotless sinless life
"Which of you convicts Me of sin? And if I tell the truth, why do you not believe Me?
2 Cor 5:21
For He made Him who knew no sin to be sin for us, that we might be made the righteousness of God in Him.
For we do not have a High Priest who cannot sympathize with our weaknesses, but was in all points tempted as we are, yet without sin.
25 Therefore He is also able to save to the uttermost those who come to God through Him, since He always lives to make intercession for them.26 For such a High Priest was fitting for us, who is holy, harmless, undefiled, separate from sinners, and has become higher than the heavens;
3 'If his offering is a burnt sacrifice of the herd, let him offer a male without blemish; he shall offer it of his own free will at the door of the tabernacle of meeting before the LORD.4 'Then he shall put his hand on the head of the burnt offering, and it will be accepted on his behalf to make atonement for him.5 'He shall kill the bull before the LORD; and the priests, Aaron's sons, shall bring the blood and sprinkle the blood all around on the altar that is by the door of the tabernacle of meeting.
21 'And whoever offers a sacrifice of a peace offering to the LORD, to fulfill his vow, or a freewill offering from the cattle or the sheep, it must be perfect to be accepted; there shall be no defect in it.

13 For if the blood of bulls and of goats, and the ashes of an heifer sprinkling the unclean, sanctifieth to the purifying of the flesh: 14 How much more shall the blood of Christ, who through the eternal Spirit offered himself without spot to God, purge your conscience from dead works to serve the living God?
1 Peter 1:18-20
18 Forasmuch as ye know that ye were not redeemed with corruptible things, as silver and gold, from your vain conversation received by tradition from your fathers; 19 But with the precious blood of Christ, as of a lamb without blemish and without spot: 20 Who verily was foreordained before the foundation of the world, but was manifest in these last times for you,
