John 1:49

Nathanael wonders how Christ should know him, having not been of his familiar acquaintance. Christ tells him he saw him under the fig tree, before ever Philip called him. That was a very hot country, wherein people sought shadowy places; hence we read of sitting under their own vines and fig trees, Mic 4:4 Zec 3:10; and it is likely that those being two luxuriant plants, that had large leaves, and ran out in long boughs, in hot weather they might under the covert of these plants not only sit as in an arbour to converse one with another, but also perform religious duties. Whether Christ saw him there eating and drinking, or conversing with friends, or reading, or praying, the Scripture saith not, and it is but vainly guessed; it is enough that by his telling this to him, he let him know that he saw him, though he was not in his view, and so was omnipresent and omniscient. Christ seeth us, where we are, and what we do, when we see not him; and he seeth our hearts, whether they be single or double, plain, or false and deceitful; which as in many cases it affords us much comfort, so it admonishes us to be at all times in the fear of the Lord.

(3.) Nathanael hereby obtained a full assurance of faith in Jesus Christ, expressed in that noble acknowledgment (v. 49): Rabbi, thou art the Son of God, thou art the king of Israel; that is, in short, thou art the true Messiah. Observe here, [1.] How firmly he believed with the heart. Though he had lately laboured under some prejudices concerning Christ, they had now all vanished. Note, The grace of God, in working faith, casts down imaginations. Now he asks no more, Can any good thing come out of Nazareth? For he believes Jesus of Nazareth to be the chief good, and embraces him accordingly. [2.] How freely he confessed with the mouth. His confession is made in form of an adoration, directed to our Lord Jesus himself, which is a proper way of confessing our faith. First, He confesses Christ's prophetical office, in calling him Rabbi, a title which the Jews commonly gave to their teachers. Christ is the great rabbi, at whose feet we must all be brought up. Secondly, He confesses his divine nature and mission, in calling him the Son of God (that Son of God spoken of Ps 2 7); though he had but a human form and aspect, yet having a divine knowledge, the knowledge of the heart, and of things distant and secret, Nathanael thence concludes him to be the Son of God. Thirdly, He confesses, "Thou art the king of Israel; that king of Israel whom we have been long waiting for." If he be the Son of God, he is king of the Israel of God. Nathanael hereby proves himself an Israelite indeed that he so readily owns and submits to the king of Israel.

Verses 43-51 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.
