"He claims to forgive sins. He says He has always existed. He says He is coming to judge the world at the end of time."

Christ claimed to forgive sins

Luke 5: 20-25: And when he saw their faith, he said, "Man, your sins are forgiven you." And the scribes and the Pharisees began to question, saying, "Who is this who speaks blasphemies? Who can forgive sins but God alone?" When Jesus perceived their thoughts, he answered them, "Why do you question in your hearts? Which is easier, to say, 'Your sins are forgiven you,' or to say, 'Rise and walk'? But that you may know that the Son of Man has authority on earth to forgive sins"—he said to the man who was paralyzed—"I say to you, rise, pick up your bed and go home." And immediately he rose up before them and picked up what he had been lying on and went home, glorifying God.

Luke 7:48-50: And he said to her [a prostitute], "Your sins are forgiven." Then those who were at table with him began to say among themselves, "Who is this, who even forgives sins?" And he said to the woman, "Your faith has saved you; go in peace."

Christ claimed to have always existed

John 8:56-58: “Your father Abraham rejoiced that he would see my day. He saw it and was glad.” So the Jews said to him, “You are not yet fifty years old, and have you seen Abraham?” Jesus said to them, “Truly, truly, I say to you, before Abraham was, I am.”

John 17:1, 5: When Jesus had spoken these words, he lifted up his eyes to heaven, and said, ". . . Father, glorify me in your own presence with the glory that I had with you before the world existed.”

Christ claimed that He is coming to judge the world at the end of time

John 5:19, 22-24, 27-30: So Jesus said to them, “. . . The Father judges no one, but has given all judgment to the Son, that all may honor the Son, just as they honor the Father. Whoever does not honor the Son does not honor the Father who sent him. Truly, truly, I say to you, whoever hears my word and believes him who sent me has eternal life. He does not come into judgment, but has passed from death to life. . . . And he has given him authority to execute judgment, because he is the Son of Man. Do not marvel at this, for an hour is coming when all who are in the tombs will hear his voice and come out, those who have done good to the resurrection of life, and those who have done evil to the resurrection of judgment. I can do nothing on my own. As I hear, I judge, and my judgment is just, because I seek not my own will but the will of him who sent me.”
