John 3:30

"He must increase, but I must decrease." That is to say, "What is mine has now come to a stand, and has henceforth ceased, but what is His increaseth; for that which ye fear shall not be now only, but much more as it advances. And it is this especially which shows what is mine the brighter! for this end I came, and I rejoice that what is His hath made so great progress, and that those things have come to pass on account of which all that I did was done." Seest thou how gently and very wisely he softened down their passion, quenched their envy, showed them that they were undertaking impossibilities, a method by which wickedness is best checked? For this purpose it was ordained, that these things should take place while John was yet alive and baptizing, in order that his disciples might have him as a witness of the superiority of Christ, and that if they should not believe, they might be without excuse. For John came not to say these words of his own accord, nor in answer to other enquirers, but they asked the question themselves, and heard the answer. For if he had spoken of himself, their belief would not have been equal to the self-condemning judgment which they received when they heard him answer to their question; just as the Jews also, in that they sent to him from their homes, heard what they did, and yet would not believe, by this especially deprived themselves of excuse.

(Tr. xxv. c. 4, 5) What meaneth this, He must increase? God neither increases, nor decreases. And John and Jesus, according to the flesh, were of the same age: for the six months' difference between them is of no consequence. This is a great mystery. Before our Lord came, men gloried in themselves; He came in no man's nature, that the glory of man might be diminished, and the glory of God exalted. For He came to remit sins upon man's confession: a man's confession, a man's humility, is God's pity, God's exaltation. This truth Christ and John proved, even by their modes of suffering: John was beheaded, Christ was lifted up on the cross. Then Christ was born, when the days begin to lengthen; John, when they begin to shorten. Let God's glory then increase in us, and our own decrease, that ours also may increase in God. But it is because thou understandest God more and more, that He seemeth to increase in thee: for in His own nature He increaseth not, but is ever perfect: even as to a man cured of blindness, who beginneth to see a little, and daily seeth more, the light seemeth to increase, whereas it is in reality always at the fall, whether he seeth it or not. In like manner the inner man maketh advancement in God, and it seemeth as if God were increasing in Him; but it is He Himself that decreaseth, falling from the height of His own glory, and rising in the glory of God.

"He must increase, but I must decrease." What is this? He must be exalted, but I must be humbled. How is Jesus to increase? How is God to increase? The perfect does not increase. God neither increases nor decreases. For if He increases, He is not perfect; if He decreases, he is not God. And how can Jesus increase, being God? If to man's estate, since He deigned to be man and was a child; and, though the Word of God, lay an infant in a manger; and, though His mother's Creator, yet sucked the milk of infancy of her: then Jesus having grown in age of the flesh, that perhaps is the reason why it is said, "He must increase, but I must decrease." But why in this? As regards the flesh, John and Jesus were of the same age, there being six months between them: they had grown up together; and if our Lord Jesus Christ had willed to be here longer before His death, and that John should be here with Him, then, as they had grown up together, so would they have grown old together: in what way, then, "He must increase but I must decrease"? Above all, our Lord Jesus Christ being now thirty years old, does a man who is already thirty years old still grow? From that same age, men begin to go downward, and to decline to graver age, thence to old age. Again, even had they both been lads, he would not have said, "He must increase," but, We must increase together. But now each is thirty years of age. The interval of six months makes no difference in age; the difference is discovered by reading rather than by the look of the persons.

What means, then, "He must increase, but I must decrease"? This is a great mystery! Before the Lord Jesus came, men were glorying of themselves; He came a man, to lessen man's glory, and to increase the glory of God. Now He came without sin, and found all men in sin. If thus He came to put away sin, God may freely give, man may confess. For man's confession is man's lowliness: God's pity is God's loftiness. Therefore, since He came to forgive man his sins, let man acknowledge his own lowliness and let God show His pity. "He must increase, but I must decrease:" that is, He must give, but I must receive; He must be glorified, but I must confess. Let man know his own condition, and confess to God; and hear the apostle as he says to a proud, elated man, bent on extolling himself: "What hast thou that thou didst not receive? And if thou didst receive it, why dost thou glory as if thou didst not receive it?" Then let man understand that he has received; and when he would call that his own which is not his, let him decrease: for it is good for him that God be glorified in him. Let him decrease in himself, that he may be increased in God.

These testimonies and this truth, Christ and John signified by their deaths. For John was lessened by the head: Christ was exalted on the cross; so that even there it appeared what this is, "He must increase, but I must decrease." Again, Christ was born when the days were just beginning to lengthen; John was born when they began to shorten. Thus their very creation and deaths testify to the words of John, when he says, "He must increase, but I must decrease." May the glory of God then increase in us, and our own glory decrease, that even ours may increase in God! For this is what the apostle says, this is what Holy Scripture says: "He that glorieth, let him glory in the Lord." Wilt thou glory in thyself? Thou wilt grow; but grow worse in thy evil. For whoso grows worse is justly decreased. Let God, then, who is ever perfect, grow, and grow in thee. For the more thou understandest God, and apprehendest Him, He seems to be growing in thee; but in Himself He grows not, being ever perfect. Thou didst understand a little yesterday; thou understandest more to-day, wilt understand much more to-morrow: the very light of God increases in thee: as if thus God increases, who remains ever perfect. It is as if one's eyes were being cured of former blindness, and he began to see a little glimmer of light, and the next day he saw more, and the third day still more: to him the light would seem to grow; yet the light is perfect, whether he see it or not. Thus it is also with the inner man: he makes progress indeed in God, and God seems to be increasing in him; yet man himself is decreasing, that he may fall from his own glory, and rise into the glory of God.
