31 The Jewish leaders took up stones again to stone him. 32 Jesus answered them, “I have shown you many good works from my Father. For which of those works do you stone me?”

33 The Jews answered him, “We don’t stone you for a good work, but for blasphemy: because you, being a man, make yourself God.”

34 Jesus answered them, “Isn’t it written in your law, ‘I said, you are gods?’ 35 If he called them gods, to whom the word of God came (and the Scripture can’t be broken), 36 do you say of him whom the Father sanctified and sent into the world, ‘You blaspheme,’ because I said, ‘I am the Son of God?’ 37 If I don’t do the works of my Father, don’t believe me. 38 But if I do them, though you don’t believe me, believe the works; that you may know and believe that the Father is in me, and I in the Father.”

39 They sought again to seize him, and he went out of their hand. 40 He went away again beyond the Jordan into the place where John was baptizing at first, and there he stayed. 41 Many came to him. They said, “John indeed did no sign, but everything that John said about this man is true.” 42 Many believed in him there.

John 10:31-42 - World English Bible

Why did people believe in Jesus? This passage from John 10 presented several reasons: his "works" and the testimony of others (like the Baptist) about him. Ultimately, THE reason to believe in him lay in his relationship with the Father. Of course, this reason was the most controversial. Was his claim to be the "Son of God" blasphemous? After all, he described his Son-ship not only in terms of intimacy, but in terms of equality; he defended his assertion with Psalm 82:6 ("I said, “You are gods, all of you are sons of the Most High."), a hymn that referred more to celestial powers ("gods") than humans. Nonetheless, he used the psalm verse to deflect his critics' charge of blasphemy, while insisting on his unique place with his Father. His claim as the "Son of God" would lead to his crucifixion and the revelation of his glory on the cross.
