Jesus Christ: The sacrifice in our place.

Jesus died on the cross and received the punishment that every human being deserved as a consequence of sin.
29 The next day John saw Jesus coming toward him and said, "Behold, the Lamb of God, who takes away the sin of the world. 30 This is the one I spoke of when I said, 'After me comes a man who is preferred before me, for he was before me.' 31 I did not know him, but I came baptizing with water so that he might be revealed to Israel." 32 John also bore witness, saying, "I saw the Spirit descending like a dove from heaven, and it remained on him." 33 I did not know him, but he who sent me to baptize with water said to me, 'On whomever you see the Spirit descending and remaining, this is the one who baptizes with the Holy Spirit.' 34 And I saw and have borne witness that this is the Son of God." 35 The next day John was standing there again with two of his disciples. 36 And looking at Jesus as he walked, he said, "Behold, the Lamb of God!" John 1:29-36
In the Bible, we find different names given to Jesus, sometimes Messiah, Lord, Christ, Teacher, Rabbi, but there is one that is perhaps the least common in today's world, which is, so to speak, the Lamb of God. We generally have limited knowledge of both the culture and history of the Jewish people, so our understanding of this name designated for Jesus Christ is often limited. However, the Israelites of Jesus' time knew this meaning very well, since in ancient times, lambs, the best lambs, were destined to be sacrificed for the forgiveness of sins.
God's dealing with human sin has always been through sacrifice. Let's remember, for example, when Adam and Eve sinned, they were covered with animal skin, and for this, an animal was sacrificed. In this way, not only their nakedness was covered, but also their shame. Later, Passover was celebrated, where each Israelite marked their doorstep with blood, and this blood came from the sacrifice of an animal.
The Lord spoke to Moses and Aaron in the land of Egypt, saying: 2 This month shall be the beginning of months for you; it shall be the first month of the year for you. 3 Say to all the congregation of Israel, On the tenth of this month each man is to take for himself a lamb according to the households of his fathers, a lamb per household. 4 But if the household is too small to eat a lamb, then he and his nearest neighbor shall take one according to the number of persons; according to what each man has eaten, you shall make a count of the lamb. 5 The animal shall be without blemish, a one-year-old male; you shall take it from the sheep or the goats. 6 You shall keep it until the fourteenth day of this month, and all the congregation of the people of Israel shall slaughter it at twilight. 7 They shall take some of the blood and put it on the two doorposts and on the lintel of the houses where they eat it.
Exodus 12:1-7
Then we see the sacrifice that would atone for sin, thus redeeming all of humanity. This is definitely the supreme sacrifice of the Lamb of God who takes away the sin of the world.
