What does John 7:7 mean?
Jesus' brothers are teasing Him about His public ministry and the sudden departure of many of His disciples (John 6:66). In their minds, Jesus ought to go to the Feast of Booths in Jerusalem and perform more magic tricks, to regrow His following. This shallow, teasing attitude is grounded in their lack of belief in Christ and His ministry (John 7:5). Not until after His resurrection will some of His siblings—at least two, James and Jude—become believers.Jesus responded in the prior verse by referring to the timetable of God. In the future, Jesus will openly declare Himself the Messiah (John 12:12–15). He will recognize that His ultimate purpose is about to be fulfilled (John 17:1). For now, however, He will act to follow God's will, instead of chasing publicity.
Jesus' brothers have no such restrictions, for two reasons. First, they are already living in "their time." They can move about the world without much consequence. Secondly, they do not face the spiritual resistance which Jesus encounters. Christ's ministry confronts sin and hypocrisy. As shown over and over in Scripture, a common response to conviction is not repentance, but hatred and violence. Both in Jesus' earthly ministry and in the work of Christianity, the world often responds in the same way to the gospel: with persecution, instead of submission.
