43 The next day Jesus decided to go to Galilee. When he got there, he ran across Philip and said, "Come, follow me." 44 (Philip's hometown was Bethsaida, the same as Andrew and Peter.) 45 Philip went and found Nathanael and told him, "We've found the One Moses wrote of in the Law, the One preached by the prophets. It's Jesus, Joseph's son, the one from Nazareth!" 46 Nathanael said, "Nazareth? You've got to be kidding." But Philip said, "Come, see for yourself." 47 When Jesus saw him coming he said, "There's a real Israelite, not a false bone in his body." 48 Nathanael said, "Where did you get that idea? You don't know me." Jesus answered, "One day, long before Philip called you here, I saw you under the fig tree." 49 Nathanael exclaimed, "Rabbi! You are the Son of God, the King of Israel!" 50 Jesus said, "You've become a believer simply because I say I saw you one day sitting under the fig tree? You haven't seen anything yet! 51 Before this is over you're going to see heaven open and God's angels descending to the Son of Man and ascending again."

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.
