His Blood is Spirit and it is Life:
John 6:56 He that eateth my flesh, and drinketh my blood, dwelleth in me, and I in him.
63 It is the spirit that quickeneth; the flesh profiteth nothing: the words that I speak unto you, they are spirit, and they are life.
If you drink His Doctrine, His Word and His Truth, you will confess and forsake, He will forgive and cleanse you from all unrighteousness.
Not by carnal blood, but by Spirit and Life.
Yes, there was the same forgiveness as today, because the LORD does not change: Repentance and ammendment:
Ezekiel 18:21 But if the wicked will turn from all his sins that he hath committed, and keep all my statutes, and do that which is lawful and right, he shall surely live, he shall not die.
27 Again, when the wicked man turneth away from his wickedness that he hath committed, and doeth that which is lawful and right, he shall save his soul alive.
Ezekiel 33:14 Again, when I say unto the wicked, Thou shalt surely die; if he turn from his sin, and do that which is lawful and right;
15 If the wicked restore the pledge, give again that he had robbed, walk in the statutes of life, without committing iniquity; he shall surely live, he shall not die.
19 But if the wicked turn from his wickedness, and do that which is lawful and right, he shall live thereby.
