19 Yet a little while, and the world will see me no more, but you will see me; because I live, you will live also. 20 In that day you will know that I am in my Father, and you in me, and I in you. 21 He who has my commandments and keeps them, he it is who loves me; and he who loves me will be loved by my Father, and I will love him and manifest myself to him." 22 Judas (not Iscariot) said to him, "Lord, how is it that you will manifest yourself to us, and not to the world?" 23 Jesus answered him, "If a man loves me, he will keep my word, and my Father will love him, and we will come to him and make our home with him. 24 He who does not love me does not keep my words; and the word which you hear is not mine but the Father's who sent me.
Matthew Henry's Commentary on John 14:19-24
Commentary on John 14:18-24
(Read John 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.
