19 "I am telling you now before it happens, so that when it does happen you will believe that I am who I am.
19 Now
19 I am telling you this now, before it takes place, that when it does take place you may believe that I am he.
19 "I'm telling you all this ahead of time so that when it happens you will believe that I am who I say I am.
19 Now I tell you before it comes, that when it does come to pass, you may believe that I am He.
19 I tell you this beforehand, so that when it happens you will believe that I AM the Messiah.
29 I have told you now before it happens, so that when it does happen you will believe.
29 And now I have told you before it come to pass, that, when it is come to pass, ye might believe.
29 And now I have told you before it takes place, so that when it does take place you may believe.
29 "I've told you this ahead of time, before it happens, so that when it does happen, the confirmation will deepen your belief in me.
29 And now I have told you before it comes, that when it does come to pass, you may believe.
29 I have told you these things before they happen so that when they do happen, you will believe.
(Read John 14:28-31)
Christ raises the expectations of his disciples to something beyond what they thought was their greatest happiness. His time was now short, he therefore spake largely to them. When we come to be sick, and to die, we may not be capable of talking much to those about us; such good counsel as we have to give, let us give while in health. Observe the prospect Christ had of an approaching conflict, not only with men, but with the powers of darkness. Satan has something in us to perplex us with, for we have all sinned; but when he would disturb Christ, he found nothing sinful to help him. The best evidence of our love to the Father is, our doing as he has commanded us. Let us rejoice in the Saviour's victories over Satan the prince of this world. Let us copy the example of his love and obedience.
Matthew Henry's Commentary on John 13:19
Commentary on John 13:18-30
(Read John 13:18-30)
Our Lord had often spoken of his own sufferings and death, without such trouble of spirit as he now discovered when he spake of Judas. The sins of Christians are the grief of Christ. We are not to confine our attention to Judas. The prophecy of his treachery may apply to all who partake of God's mercies, and meet them with ingratitude. See the infidel, who only looks at the Scriptures with a desire to do away their authority and destroy their influence; the hypocrite, who professes to believe the Scriptures, but will not govern himself by them; and the apostate, who turns aside from Christ for a thing of naught. Thus mankind, supported by God's providence, after eating bread with Him, lift up the heel against Him! Judas went out as one weary of Jesus and his apostles. Those whose deeds are evil, love darkness rather than light.
