It is the cross. This is not the usual picture of glory we carry in our heads. Glory is winning the lottery. Glory is making a killing in the stock market. D.C. Glory is a display of overwhelming military power or the defeat of the enemy.
Glory is a shopping mall with hundreds of stores filled with the latest merchandise.
Glory is wealth and power and excess. But Jesus' glory is doing God's will. Jesus' glory is standing with the marginalized. Jesus' glory is in giving himself up for our sake. Jesus' glory is the cross.
