But above all let us bear in mind that it is a new birth that is required; that no care spent on our conduct, no improvement and refinement of the natural man, suffices. For flying it is not an improved caterpillar that is needed, it is a butterfly; it is not a caterpillar of finer colour or more rapid movement or larger proportions, it is a new creature. We recognise that in this and that man we meet there is something more than men naturally have; we perceive in them a taming, chastening, inspiring principle. We rejoice all the more when we see it, because we know that no man can give it, but only God. And we mourn its absence because even when a man is dutiful, affectionate, temperate, honourable, yet if he have not grace, if he have not that peculiar tone and colour which overspread the whole character, and show that the man is living in the light of Christ, and is moved by love to God, we instinctively feel that the defect is radical, that as yet he has not come into connection with the Eternal, that there is that awanting for which no natural qualities, however excellent, can compensate--nay, the more lovely and complete the natural character is, the more painful and lamentable is the absence of grace, of Spirit.
"Nicodemus answered and said unto Him, How can these things be? Jesus answered and said unto him, Art thou the teacher of Israel, and understandest not these things? Verily, verily, I say unto thee, We speak that we do know, and bear witness of that we have seen; and ye receive not our witness. If I told you earthly things, and ye believe not, how shall ye believe, if I tell you heavenly things? And no man hath ascended into heaven, but He that descended out of heaven, even the Son of man, which is in heaven. And as Moses lifted up the serpent in the wilderness, even so must the Son of man be lifted up: that whosoever believeth may in Him have eternal life. For God so loved the world that He gave His only begotten Son, that whosoever believeth on Him should not perish, but have eternal life. For God sent not the Son into the world to judge the world; but that the world should be saved through Him. He that believeth on Him is not judged: he that believeth not hath been judged already, because he hath not believed on the name of the only begotten Son of God. And this is the judgment, that the light is come into the world, and men loved the darkness rather than the light; for their works were evil. For every one that doeth ill hateth the light, and cometh not to the light, lest his works should be reproved. But he that doeth the truth cometh to the light, that his works may be made manifest, that they have been wrought in God."--JOHN iii. 9-21.
There are two great obstacles to human progress, two errors which retard the individual and the race, two inborn prejudices which prevent men from choosing and entering into true and lasting prosperity. The first is that men will always persist in seeking their happiness in something outside themselves; the second is that even when they come to see where true happiness lies they cannot find the way to it. In our Lord's time even wise and godly people thought the permanent glory and happiness of men were to be found in a free state, in self-government, lightened taxes, impregnable fortresses, and a purified social order. And they were not altogether wrong; but the way to this condition, they thought, lay through the enthronement of a strong-handed monarch, who could gather round his throne wise counsellors and devoted followers. This was the form of worldliness which our Lord had to contend with. This was the tendency of the unspiritual mind in His day. But in every generation and in all men the same radical misconceptions exist, although they may not appear in the same forms.
