John 10:26

In the second branch of this answer, Christ points out the true cause of their infidelity; Which is, not the obscurity of his doctrine, but their not being of his sheep; that is, not as yet converted, and not only so, but evidenced to be reprobates, if they continue in that sinne. And by this he prevents a great objection, and the scandal of their not embracing him, who were eminent in that Church; and sheweth, that this contempt did not reflect on him, but on themselves. Whence learn, 1. Despisers of Christ will get no affront rubbed upon him, but all the prejudice and disgrace is their own; Therefore doth he clear here, that their unbelief reflected on themselves. 2. Albeit Christ will not reveal unto men his eternal purposes concerning them, till first they declare what is in their own hearts; Yet as he knoweth who are elect, and who are reprobates, and as he hath recorded in his Word the evidences of men that are reprobates, or, at least, in a reprobate condition: So he could have wicked men affected and affrighted by seeing such evidences in themselves; Therefore, upon their unbelief, he leads them up to see, ye are not of my sheep, that they might consider how deep their sinne drew. 3. Mens unbeliefe under the means of faith, is a clear evidence of their being in a reprobate condition, and their continuance therein, an evidence that they are reprobates; for, ye beleeve not, because ye are not of my sheep. 4. Christs doctrine is not yea and nay, but still the same; and it is mens great fault, that being often warned of their danger, yet they mark it not, nor make use of it: Therefore doth he subjoyne, As I said unto you, to wit, in the foregoing parable, where it had been insinuate, and frequently elsewhere he had pointed out their dangerous condition. And by this he would tell them that his thoughts of them were still the same, and that it was their great stupidity, not to take notice of what he had so often repeated.
