Here Jesus points out the painful reality that there are people who do not love him. This shortcoming is revealed because they do not adhere to his Word. They do not experience the wonderful nearness of God in their earthly lives.
In the second part of this verse, Jesus points out to his disciples that Thursday night—and to us, centuries later—that the words he speaks have a high origin. God the Father is speaking through him. Shortly before, Jesus had said this emphatically, I have not spoken on my own authority, but the Father who sent me has given me a commandment—what to say and what to speak
(John 12:49; see also John 3:34; John 8:28; John 15:15). This should encourage us to take Jesus' words seriously. In Jesus, we encounter God. The apostle Paul can therefore write: We thank God constantly for this that when you received the word of God, which you heard from us, you accepted it not as the word of men, but as what it really is: the word of God which is at work in you believers.
(1 Thessalonians 2:13)
Precisely this high origin marks their reliability. We have something to hold on to, both in life and in death, in what God speaks and promises. Martin Luther, the reformer of the church in the sixteenth century, understood this very well when he composed A mighty fortress is our God.
The fourth stanza of this hymn therefore begins with the words:
That word above all earthly powers—
no thanks to them—abideth;
the Spirit and the gifts are ours
through him who with us sideth.
24 Celui qui ne m'aime pas ne garde point mes paroles. Et la parole que vous entendez n'est pas de moi, mais du Père qui m'a envoyé.
