What does John 6:15 mean?
In a practical sense, the massive crowd following Jesus (John 6:2) has the correct response to His latest, most public miracle. They want to make Him King, in part because they recognize His prophetic fulfillment (John 6:14). However, their approach is in error on several accounts.First and foremost, the vast majority of these people are not heralding Jesus as King because they recognize their need for God or because they believe in His message. They are responding to the spectacle of a miracle, the handout of free food (John 6:26), and the prospect of shrugging off Roman occupation (John 11:48; 18:31). When Jesus puts his miracles—which the gospel of John calls signs—into proper perspective, most of those adoring Him now will simply turn and walk away (John 6:66).
Secondly, this is not the moment Jesus is meant to be publicly, openly declared as King. That moment is about a year away (John 6:4), at the triumphal entry just prior to His crucifixion (John 12:12–15). Throughout the gospel of John, Jesus shows an iron-clad devotion to God's divine schedule (John 7:6; John 16:25).
