“John 1:29 - “29 The next day John saw Jesus coming toward him and said, “Look, the Lamb of God, who takes away the sin of the world!””
And what is it you are trying to prove? That the sin of the reprobate, including the sin of unbelief, is taken away? Is there no definite recipient of atonement?
Humans are spiritual beings and thereby possess capabilities that the time and space bound universe we see, composed of matter and energy, doesn’t. Things that are true of a rock or a tree are not true of a soul.
Exodus 30: 6 Put the altar in front of the curtain that is before the ark of the Testimony--before the atonement cover that is over the Testimony--where I will meet with you. 7 "Aaron must burn fragrant incense on the altar every morning when he tends the lamps. 8 He must burn incense again when he lights the lamps at twilight so incense will burn regularly before the LORD for the generations to come. 9 Do not offer on this altar any other incense or any burnt offering or grain offering, and do not pour a drink offering on it. 10 Once a year Aaron shall make atonement on its horns. This annual atonement must be made with the blood of the atoning sin offering for the generations to come. It is most holy to the LORD."
That atonement was for the entire nation, however, it was effective only for the faithful.
Jeremiah 7: 21 " 'This is what the LORD Almighty, the God of Israel, says: Go ahead, add your burnt offerings to your other sacrifices and eat the meat yourselves! 22 For when I brought your forefathers out of Egypt and spoke to them, I did not just give them commands about burnt offerings and sacrifices, 23 but I gave them this command: Obey me, and I will be your God and you will be my people. Walk in all the ways I command you, that it may go well with you. 24 But they did not listen or pay attention; instead, they followed the stubborn inclinations of their evil hearts. They went backward and not forward. 25 From the time your forefathers left Egypt until now, day after day, again and again I sent you my servants the prophets. 26 But they did not listen to me or pay attention. They were stiff-necked and did more evil than their forefathers.' 27 "When you tell them all this, they will not listen to you; when you call to them, they will not answer. 28 Therefore say to them, 'This is the nation that has not obeyed the LORD its God or responded to correction. Truth has perished; it has vanished from their lips. 29 Cut off your hair and throw it away; take up a lament on the barren heights, for the LORD has rejected and abandoned this generation that is under his wrath.
