Jesus gives his final briefing to his disciples, reminding them of four truths: 1) he could only send the Spirit to them if he dies and ascends to the Father, 2) they were to show their love through their obedience, as he had, 3) they should expect life to be difficult, even when (or especially when) they were following his path, and 4) he had made it possible for them to be one with him.
