The Bible teaches this. The unique Son of God who died for humanity's sin.
Matthew 14:33Then those who were in the boat worshiped him, saying, “Truly you are the Son of God.”
Jesus went on to say, “In a little while you will see me no more, and then after a little while you will see me.”
I have seen and I testify that this is God’s Chosen One.”
35 Jesus heard that they had thrown him out, and when he found him, he said, “Do you believe in the Son of Man?”
36 “Who is he, sir?” the man asked. “Tell me so that I may believe in him.”
37 Jesus said, “You have now seen him; in fact, he is the one speaking with you.”
