Jesus told his disciples that his final great sign would be his return in glory at the end of the age. He would come this second time as Judge and Merciful Redeemer to vindicate those who accepted him as Lord and Saviour and to punish those who rejected him. Jesus declared that this last sign at the end of the world would be unmistakable. All would recognize and “see the Son of man coming in a cloud with power and great glory” (Luke 21:27). The title which Jesus most often used to describe his Messianic role was the expression “Son of Man”. This title comes from the Book of the prophet Daniel, chapter 7. The image of a “Son of man coming in a cloud with power and great glory” was given in a vision where the prophet Daniel saw heaven opened before the throne of God (Daniel 7:13-14). In this vision God showed Daniel a royal investiture of a human king before God’s throne. This king was invested with God’s authority and was given power to judge and rule over the whole earth. His reign would last for all ages.
