In this passage, Jesus is preparing his disciples for his impending death and resurrection, and he is assuring them that he has foretold these events so that they may believe in him and his teachings.

The context of this verse is important to understand its significance. In the preceding verses, Jesus speaks about going to prepare a place for his followers in his Father's house. He promises that he will come again to take them to be with him. He also reassures them that they will know the way to where he is going. It is in this context that Jesus says, "And now I have told you before it come to pass, that, when it is come to pass, ye might believe." He is emphasizing the importance of his teachings and prophecies, and he wants his disciples to have faith in him and his word.

This theme of belief and faith is a recurring motif in the Gospel of John, and it underscores the necessity of trusting in Jesus as the Messiah and the Savior.

Another theme in this verse is the fulfillment of prophecy. Jesus declares that he has told his disciples about the future events so that when they come to pass, they may believe.
