In John's Gospel, Jesus' brothers appear to somewhat flippantly suggest that He demonstrate certain "works" to prove or publicize Himself before His disciples in Judea:
John 7:2-5: "Now the feast of the Jews, the Feast of Booths, was near. 3Therefore His brothers said to Him, 'Leave here and go into Judea, so that Your disciples also may see Your works which You are doing. 4For no one does anything in secret when he himself seeks to be known publicly. If You do these things, show Yourself to the world.' 5For not even His brothers were believing in Him." (emphasis added).
This seems especially peculiar given Christ recent notoriety. Were they suggesting this facetiously, perhaps reflecting on previous behavior that left them deeply skeptical — maybe their attempts to "save Jesus from Himself" as we read in Mark's Gospel?
Mark 3:21: "When [Jesus'] own people heard of [the multitudes seeking Him out], they went out to take custody of Him; for they were saying, 'He has lost His senses.'"
This timeline may not be quite correct. (If so, I would appreciate someone pointing that out.) Nonetheless, how should we view Christ's own brothers' petty recommendations as anything but irreverent since "they did not believe Him" when they offered such "valuable advice"?
