What does John 14:31 mean?

In several statements, Jesus emphasized that everything He did was according to the explicit will of God (John 3:35; 5:30; 12:49). In those remarks, Christ was mostly speaking of His teaching and miracles (John 5:36). Here, the words flow directly from the comment Jesus made in verse 30. There, He said that Satan—"the ruler of this world" was coming for Him (John 14:30). However, Jesus also made it clear that Satan had no actual power over Him.

The first phrase of this verse, then, is a continuation of the last phrase in verse 30. Satan has no control over Jesus, rather, Jesus acts according to His own will and His own power. That means obeying the will of God the Father (John 12:49–50), even when it conflicts with the human aspects of Jesus' nature (John 12:27; Matthew 26:39; Luke 22:42).

Once again, Jesus connects the ideas of love and obedience (John 14:15, 21). His submission to the will of God is evidence that His message is true (John 5:19).

Jesus' instruction to go probably refers to leaving the upper room, heading back to the disciples' camp site on the Mount of Olives. This is where Judas plans to bring authorities to arrest Jesus (John 11:57; 13:2). John doesn't include explicit information about where Jesus was during each phase of His discourse. However, the start of chapter 18 suggests that what's contained in chapters 15, 16, and 17 is stated before the group gets to Gethsemane (John 18:1).
