{7} Judas saith unto him, not Iscariot, Lord, how is it that thou wilt manifest thyself unto us, and not unto the world?

(7) We must not ask why the gospel is revealed to some rather than to others, but we must rather take heed that we embrace Christ who is offered unto us, and that we truly love him, that is to say, that we give ourselves wholly to obeying him.

People's New Testament

14:21-23 He that hath my commandments, etc. The conditions on which Christ will be present in each soul, seen, and enjoyed, are here given: (1) One must love Christ; (2) so love him that he will obey from the heart his commandments; (3) this loving, obedient soul will be loved of the Father; (4) Christ will love him; (5) both the Father and the Son will manifest themselves to him; (6) this manifestation is by their coming and abiding in him through the Helper.

Jamieson-Fausset-Brown Bible Commentary

22. Judas saith . not Iscariot-Beautiful parenthesis this! The traitor being no longer present, we needed not to be told that this question came not from him. But it is as if the Evangelist had said, "A very different Judas from the traitor, and a very different question from any that he would have put. Indeed [as one in Stier says], we never read of Iscariot that he entered in any way into his Master's words, or ever put a question even of rash curiosity (though it may be he did, but that nothing from him was deemed fit for immortality in the Gospels but his name and treason)."

how . manifest thyself to us, and not to the world-a most natural and proper question, founded on Joh 14:19, though interpreters speak against it as Jewish.

Matthew Henry's Concise Commentary

14:18-24 Christ promises that he would continue his care of his disciples. I will not leave you orphans, or fatherless, for though I leave you, yet I leave you this comfort, I will come to you. I will come speedily to you at my resurrection. I will come daily to you in my Spirit; in the tokens of his love, and visits of his grace. I will come certainly at the end of time. Those only that see Christ with an eye of faith, shall see him for ever: the world sees him no more till his second coming; but his disciples have communion with him in his absence. These mysteries will be fully known in heaven. It is a further act of grace, that they should know it, and have the comfort of it. Having Christ's commands, we must keep them. And having them in our heads, we must keep them in our hearts and lives. The surest evidence of our love to Christ is, obedience to the laws of Christ. There are spiritual tokens of Christ and his love given to all believers. Where sincere love to Christ is in the heart, there will be obedience. Love will be a commanding, constraining principle; and where love is, duty follows from a principle of gratitude. God will not only love obedient believers, but he will take pleasure in loving them, will rest in love to them. He will be with them as his home. These privileges are confined to those whose faith worketh by love, and whose love to Jesus leads them to keep his commandments. Such are partakers of the Holy Spirit's new-creating grace.
