Here, Jesus is speaking of His crucifixion on the Cross…the first step of His exaltation via His resurrection and ascension. The Cross of Jesus was as Isaiah described a sign or a banner of hope (Isaiah 11:10) that exerts a universal attraction & draw to all people of all nationalities without distinction. So our job is to continue to lift up the Name of Jesus…exalting & glorifying the work He did on the Cross for all mankind.
