João 7:6

Jesus replied that it was not the right time (Gr. kairos) for Him to go to Jerusalem, the Father’s time (cf. John 2:4). However, they could go to the feast at any time (Gr. kairos). They were not on a mission and timetable from God as He was.

"John’s picture of Jesus is of one steadily moving on to meet his divinely appointed destiny." [Note: Morris, p. 352.]

Another interpretation is that Jesus meant that the time of His death was not yet at hand. However the Greek word that Jesus used when referring to His death and its consequences in John’s Gospel is always hora elsewhere, not kairos (John 2:4; John 7:30; John 8:20; John 12:23; John 12:27; John 13:1; John 17:1).
