John
King James Version (KJV)

“The next day John seeth Jesus coming unto him, and saith, Behold the Lamb of God, which taketh away the sin of the world.”
King James Version (KJV)
1:29 He seeth Jesus coming and saith, Behold the Lamb - Innocent; to be offered up; prophesied of by Isaiah, #Isa 53:7|, typified by the paschal lamb, and by the daily sacrifice: The Lamb of God - Whom God gave, approves, accepts of; who taketh away - Atoneth for; the sin - That is, all the sins: of the world - Of all mankind. Sin and the world are of equal extent.
Joh 1:29 The next day John seeth Jesus. Here Jesus first appears, in person, in John's account, who omits all the details given by Matthew and Luke of his earlier life. He was now thirty years old, and came from Galilee to Jordan to be baptized of John. This interview was after the baptism (Joh 1:33), and probably after the Temptation. Behold the Lamb of God. Innocent like the lamb, to be offered as a lamb, "led as a lamb to the slaughter" (Isa 53:7). The lamb was commonly used as a sin offering (Le 4:32), and when John points to Jesus as "the" Lamb of God he can only mean that God had provided him as a sacrificial offering. The sin of the world. Not of Jews only, but of Gentiles. John points to Jesus as the world's Savior.
To be a subtitute means to die in the place of another. This means that the death of Jesus was not capricious. It's legal basis was to place Jesus in the place of all people and punish him for their crimes.
This could only take place if Jesus is the one who made us, and is therefore God. This is what David means when he says, "Open for me the gates where the righteous enter, and I will go in and thank the Lord (Jesus). Those gates lead to the presence of the Lord (Jesus), and the godly enter there. I thank you for answering my prayer and saving me!" (Psalm 118:19-21) The prophet Isaiah says the same thing in Isaiah 45:21-22: "... For there is no other God but me-a just God and a Savior-no, not one! Let all the world look to me for salvation!
What we are talking about here is self identity or personality. That is, the self identity or personality through whom God's saves us is Jesus.
