Charles Spurgeon Commentary John 12:20-22

"Now there were certain Greeks among those that went up to worship at the feast: these therefore came to Philip, who was of Bethsaida of Galilee, and asked him, saying, Sir, we would see Jesus. Philip cometh and telleth Andrew: Andrew cometh, and Philip, and they tell Jesus." — John 12:20-22 (ASV)

And there were certain Greeks among them that came up to worship at the feast: The same came therefore to Philip, which was of Bethsaida of Galilee, and desired him, saying, Sir, we would see Jesus. Philip cometh and telleth Andrew: and again Andrew and Philip tell Jesus.

Probably these persons were proselytes to the Jewish faith. They had renounced their idols, and they had come to worship the only true God; and now they had a wish to see Jesus, not out of idle curiosity, but because they felt a certain degree of respect for him.

They wanted to know more about his teaching, and to learn whether he was indeed the promised Messiah. The disciples encouraged these seekers; they would not have brought mere curiosity-mongers to their Master, but they saw that there was something better in these Greeks; so they consulted together, and their opinion was that they must tell Jesus about them.
