Fairly to face that question is to go far towards answering it. For as soon as we begin to look steadily at the facts, we find that the differences between all these other appearances and the Incarnation are so great as to raise the presumption that their origins are different. The 'gods' slipped on the appearance of humanity over their garment of deity in appearance only, and that for a moment. Jesus is 'bone of our bone and flesh of our flesh,' and is not merely 'found in fashion as a man,' but is 'in all points like as we are.' And that garb of manhood He wears for ever, and in His heavenly glory is 'the Man Christ Jesus.'
But the difference between all these other appearances of gods and the Incarnation lies in the acts to which they and it respectively led, and the purposes for which they and it respectively took place. A god who came down to suffer, a god who came to die, a god who came to be the supreme example of all fair humanities, a god who came to suffer and to die that men might have life and be victors over sin—where is he in all the religions of the world? And does not the fact that Christianity alone sets before men such a God, such an Incarnation, for such ends, make the assertion a reasonable one, that the sources of the universal belief in gods who come down among men and of the Christian proclamation that the Eternal Word became flesh are not the same, but that these are men's half-understood cries, and this is Heaven's answer?
'THE DOOR OF FAITH'
'And when they were come, and had gathered the church together, they rehearsed all that God had done with them, and how he had opened the door of faith unto the Gentiles.'—ACTS xiv. 27.
There are many instances of the occurrence of this metaphor in the New Testament, but none is exactly like this. We read, for example, of 'a great door and effectual' being opened to Paul for the free ministry of the word; and to the angel of the Church in Philadelphia, 'He that openeth and none shall shut' graciously says, 'I have set before thee a door opened, which none can shut.' But here the door is faith, that is to say faith is conceived of as the means of entrance for the Gentiles into the Kingdom, which, till then, Jews had supposed to be entered by hereditary rite.
I. Faith is the means of our entrance into the Kingdom.
The Jew thought that birth and the rite of circumcision were the door, but the 'rehearsing' of the experiences of Paul and Barnabas on their first missionary tour shattered that notion by the logic of facts. Instead of that narrow postern another doorway had been broken in the wall of the heavenly city, and it was wide enough to admit of multitudes entering. Gentiles had plainly come in. How had they come in? By believing in Jesus. Whatever became of previous exclusive theories, there was a fact that had to be taken into account. It distinctly proved that faith was 'the gate of the Lord into which,' not the circumcised but the 'righteous,' who were righteous because believing, 'should enter.'
We must not forget the other use of the metaphor, by our Lord Himself, in which. He declares that He is the Door. The two representations are varying but entirely harmonious, for the one refers to the objective fact of Christ's work as making it possible that we should draw near to and dwell with God, and the other to our subjective appropriation of that possibility, and making it a reality in our own blessed experience.
II. Faith is the means of God's entrance into our hearts.
We possess the mysterious and awful power of shutting God out of these hearts. And faith, which in one aspect is our means of entrance into the Kingdom of God, is, in another, the means of God's entrance into us. The Psalm, which invokes the divine presence in the Temple, calls on the 'everlasting doors' to be 'lifted up,' and promises that then 'the King of Glory will come in.' And the voice of the ascended Christ, the King of Glory, knocking at the closed door, calls on us with our own hands to open the door, and promises that He 'will come in.'
