Verse 26. - But when the blade was sprung up (ἐβλάστησεν ὁ χόρτος: cf. Mark 4:27), and brought forth fruit. Observe that there is no thought of the tares injuring the wheat (contrast vers. 7, 22). Then appeared the tares also.

13:24-30, 36-43 This parable represents the present and future state of the gospel church; Christ's care of it, the devil's enmity against it, the mixture there is in it of good and bad in this world, and the separation between them in the other world. So prone is fallen man to sin, that if the enemy sow the tares, he may go his way, they will spring up, and do hurt; whereas, when good seed is sown, it must be tended, watered, and fenced. The servants complained to their master; Sir, didst thou not sow good seed in thy field? No doubt he did; whatever is amiss in the church, we are sure it is not from Christ. Though gross transgressors, and such as openly oppose the gospel, ought to be separated from the society of the faithful, yet no human skill can make an exact separation. Those who oppose must not be cut off, but instructed, and that with meekness. And though good and bad are together in this world, yet at the great day they shall be parted; then the righteous and the wicked shall be plainly known; here sometimes it is hard to distinguish between them. Let us, knowing the terrors of the Lord, not do iniquity. At death, believers shall shine forth to themselves; at the great day they shall shine forth before all the world. They shall shine by reflection, with light borrowed from the Fountain of light. Their sanctification will be made perfect, and their justification published. May we be found of that happy number.But when the blade was sprung up,.... That is, the blade of the wheat; which designs the taking up, a profession of religion on principles of grace, called a profession of faith; and when right, it springs up from, and proceeds upon a work begun in the heart: and such a profession ought to be made by all that are partakers of the grace of God; and ought to be made both verbally, by a confession of the mouth, and a declaration of the work of God upon the heart, and by deeds, by submitting to the ordinances of the Gospel; and should be sincere, and from the heart, and be visible to men, and be held fast unto the end without wavering.

And brought forth fruit; which intends not the conversion of sinners, nor the performance of duties, nor the perfection of grace, but the first appearances of grace under a profession, such as sorrow for sin, after a godly sort, fear and reverence of God, great humility, much self-denial, ardent love to Christ, pantings and breathings after him, and communion with him, strong affection for the people of God, some exercise of faith on Christ, zeal for his cause and interest, and a concern to honour and glorify God.

Then appeared the tares also. They were not discernible for some time when they were first sown; they looked like good seed when they first appeared among the people of God; they seemed to have the truth of grace, as others had; their blade of profession, when it sprung up, looked like that of true wheat; but were now discernible both by their unfruitfulness in their lives and conversations, and by their bad principles, which they now endeavoured to spread, to the hurt of the churches where they were: they always appeared to be what they were to God the searcher of hearts; but now, through the zeal of true converts, to which these opposed themselves, and the fruitfulness of their lives, from which they were so very different, they became manifest to ministers and churches.
