That omniscience, as manifested here, shows us how glad Christ is when He sees anything good, anything that He can praise in any of us. 'Behold an Israelite indeed, in whom there is no guile.' Not a word about Nathanael's prejudice, not a word about any of his faults (though no doubt he had plenty of them), but the cordial praise that he was an honest, a sincere man, following after God and after truth. There is nothing which so gladdens Christ as to see in us any faint traces of longing for, and love towards, and likeness to, His own self. His omniscience is never so pleased as when beneath heaps and mountains of vanity and sin it discerns in a man's heart some poor germ of goodness and longing for His grace.
And then again, notice how we have here our Lord's omniscience set forth as cognisant of all our inward crises and struggles, 'When thou wast under the fig tree, I saw thee.' I suppose all of us could look back to some place or other, under some hawthorn hedge, or some boulder by the seashore, or some mountain-top, or perhaps in some back-parlour, or in some crowded street, where some never-to-be-forgotten epoch in our soul's history passed, unseen by all eyes, and which would have shown no trace to any onlooker, except perhaps a tightly compressed lip. Let us rejoice to feel that Christ sees all these moments which no other eye can see. In our hours of crisis, and in our monotonous, uneventful moments, in the rush of the furious waters, when the stream of our lives is caught among rocks, and in the long, languid reaches of its smoothest flow, when we are fighting with our fears or yearning for His light, or even when sitting dumb and stolid, like snow men, apathetic and frozen in our indifference, He sees us, and pities, and will help the need which He beholds.
'Think not thou canst sigh a sigh, And thy Saviour is not by; Think not thou canst weep a tear, And thy Saviour is not near.'
'When thou wast under the fig tree, I saw thee.'
III. One word more about this rapturous confession, which crowns the whole: 'Rabbi, Thou art the Son of God; Thou art the King of Israel.'
Where had Nathanael learned these great names? He was a disciple of John the Baptist, and he had no doubt heard John's testimony as recorded in this same chapter, when he told us how the voice from Heaven had bid him recognise the Messiah by the token of the descending Dove, and how he 'saw and bare record that this is the Son of God.' John's testimony was echoed in Nathanael's confession. Undoubtedly he attached but vague ideas to the name, far less articulate and doctrinal than we have the privilege of doing. To him 'Son of God' could not have meant all that it ought to mean to us, but it meant something that he saw clearly, and a great deal beyond that he saw but dimly. It meant that God had sent, and was in some special sense the Father of, this Jesus of Nazareth.
'Thou art the King of Israel,' John had been preaching, 'The Kingdom of Heaven is at hand.' The Messiah was to be the theocratic King, the King, not of 'Judah' nor of 'the Jews,' but of 'Israel,' the nation that had entered into covenant with God. So the substance of the confession was the Messiahship of Jesus, as resting upon His special divine relationship and leading to His Kingly sway.
Notice also the enthusiasm of the confession; one's ear hears clearly a tone of rapture in it. The joy-bells of the man's heart are all a-ringing. It is no mere intellectual acknowledgment of Christ as Messiah. The difference between mere head-belief and heart-faith lies precisely in the presence of these elements of confidence, of enthusiastic loyalty, and absolute submission.
