In John 14, which disciple asked why Jesus would reveal himself to them and not to the world?

Answer: Judas (not Iscariot)

Judas, not Iscariot, asked this; Jesus replied that the Father and he would make their home with anyone who loves him.

“Judas (not Iscariot) asked Him, “Lord, why are You going to reveal Yourself to us and not to the world?” Jesus replied, “If anyone loves Me, he will keep My word. My Father will love him, and We will come to him and make Our home with him.”— John 14:22-23 (BSB)
