43 The day after this, Jesus had a desire to go into Galilee. He came across Philip and said to him, Come and be my disciple. 44 Now Philip's town was Beth-saida, where Andrew and Peter came from. 45 Philip came across Nathanael and said to him, We have made a discovery! It is he of whom Moses, in the law, and the prophets were writing, Jesus of Nazareth, the son of Joseph. 46 Nazareth! said Nathanael, Is it possible for any good to come out of Nazareth? Philip said to him, Come and see. 47 Jesus saw Nathanael coming to him and said of him, See, here is a true son of Israel in whom there is nothing false. 48 Nathanael said to him, Where did you get knowledge of me? In answer Jesus said, Before Philip was talking with you, while you were still under the fig-tree, I saw you. 49 Nathanael said to him, Rabbi, you are the Son of God, you are King of Israel!

See the nature of true Christianity, it is following Jesus; devoting ourselves to him, and treading in his steps. Observe the objection Nathanael made. All who desire to profit by the word of God, must beware of prejudices against places, or denominations of men. They should examine for themselves, and they will sometimes find good where they looked for none. Many people are kept from the ways of religion by the unreasonable prejudices they conceive. The best way to remove false notions of religion, is to make trial of it. In Nathanael there was no guile. His profession was not hypocritical. He was not a dissembler, nor dishonest; he was a sound character, a really upright, godly man. Christ knows what men are indeed. Does He know us? Let us desire to know him. Let us seek and pray to be Israelites indeed, in whom is no guile; truly Christians, approved of Christ himself. Some things weak, imperfect, and sinful, are found in all, but hypocrisy belongs not to a believer's character. Jesus witnessed what passed when Nathanael was under the fig-tree. Probably he was then in fervent prayer, seeking direction as to the Hope and Consolation of Israel, where no human eye observed him. This showed him that our Lord knew the secrets of his heart. Through Christ we commune with, and benefit by the holy angels; and things in heaven and things on earth are reconciled and united together.
