John 1:43-48 The day following Jesus would go forth into Galilee, and find Philip, and saith unto him, Follow me. Now Philip was of Bethsaida, the city of Andrew and Peter. Philip find Nathanael, and saith unto him, We have found him, of whom Moses in the law, and the prophets, did write, Jesus of Nazareth, the son of Joseph. And Nathanael said unto him, Can there any good thing come out of Nazareth? Philip saith unto him, Come and see. Jesus saw Nathanael coming to him, and saith of him, Behold an Israelite indeed, in whom is no guile! Nathanael saith unto him, Whence know thou me? Jesus answered and said unto him, Before that Philip called thee, when thou was under the fig tree, I saw thee.
Philip was one of the twelve apostles (Matt. 10:3; Mar. 3:18; Lk. 6:14; Acts 1:13), a brother of Nathanael, who brings him also to Jesus. Nathanael (means gift of God) is Bartholomew, which is a patronymic of Nathaniel, also one of the twelve.
The question he asked “can there any good thing come out of Nazareth?” was because they were expecting the Messiah from Bethlehem, and not Nazareth. Never a better person came from any place on earth than Jesus Christ!
Jesus knew Nathanael’s heart through the Holy Spirit’s gift of knowledge (John 3:34; 1Cor. 12:4-11) and said that he was an Israelite in whom is no guile – he was without deceit.
Christ’s statement of seeing him by the Spirit before He could see him with His eyes convinced Nathaniel of Christ’s Sonship.
