9:26 And coming to Jerusalem - Three years after, Gal 1:18.These three years St. Paul passes over, Act 22:17, likewise.

9:27 To the apostles - Peter and James, Gal 1:18-19. And declared - He who has been an enemy to the truth ought not to be trusted till he gives proof that he is changed.

9:31 Then the Church - The whole body of Christian believers, had peace - Their bitterest persecutor being converted. And being built up - In holy, loving faith, continually increasing, and walking in - That is, speaking and acting only from this principle, the fear of God and the comfort of the Holy Ghost - An excellent mixture of inward and outward peace, tempered with filial fear.

3:18 Not in word - Only. But in deed - In action: not in tongue by empty professions, but in truth.

3:19 And hereby we know - We have a farther proof by this real, operative love. That we are of the truth - That we have true faith, that we are true children of God. And shall assure our hearts before him - Shall enjoy the assurance of his favour, and the "testimony of a good conscience toward God." The heart, in St. John's language, is the conscience. The word conscience is not found in his writings.

3:20 For if we have not this testimony, if in anything our heart, our own conscience, condemn us, much more does God, who is greater than our heart - An infinitely holier and a more impartial Judge. And knoweth all things - So that there is no hope of hiding it from him.

3:21 If our heart condemn us not - If our conscience, duly enlightened by the word and Spirit of God, and comparing all our thoughts, words, and works with that word, pronounce that they agree therewith. Then have we confidence toward God - Not only our consciousness of his favour continues and increases, but we have a full persuasion, that whatsoever we ask we shall receive of him.

3:23 And this is his commandment - All his commandments in one word. That we should believe and love - in the manner and degree which he hath taught. This is the greatest and most important command that ever issued from the throne of glory.If this be neglected, no other can be kept: if this be observed, all others are easy.

3:24 And he that keepeth his commandments - That thus believes and loves. Abideth in him, and God in him: and hereby we know that he abideth in us, by the Spirit which he hath given us - Which witnesses with our spirits that we are his children, and brings forth his fruits of peace, love, holiness. This is the transition to the treating of the Holy Spirit which immediately follows.

15:1 I am the true vine - So the true bread, Joh 6:32; that is, the most excellent.

15:2 Every one that beareth fruit, he purifieth - by obeying the truth, Pe1 1:22; and by inward or outward sufferings, Heb 12:10-11. So purity and fruitfulness help each other.That it may bear more fruit - For this is one of the noblest rewards God can bestow on former acts of obedience, to make us yet more holy, and fit for farther and more eminent service.

15:3 Ye are clean - All of you, to whom I now speak, are purged from the guilt and power of sin; by the word - Which, applied by the Spirit, is the grand instrument of purifying the soul.

15:4 Abide in me - Ye who are now pure by living faith, producing all holiness; by which alone ye can be in me.

15:5 I am the vine, ye are the branches - Our Lord in this whole passage speaks of no branches but such as are, or at least were once, united to him by living faith.

15:6 If any one abide not in me - By living faith; not by Church communion only. He may thus abide in Christ, and be withered all the time, and cast into the fire at last. He is cast out - Of the vineyard, the invisible Church. Therefore he was in it once.

15:7 If ye abide in me, ye shall ask - Prayers themselves are a fruit of faith, and they produce more fruit.

15:8 So shall ye be my disciples - Worthy of the name. To be a disciple of Christ is both the foundation and height of Christianity.
