Before Jesus Christ ascended to heaven in 33 C.E., he promised to return. He likened himself to a nobleman who went away for a long time and returned with power to rule as king. The purpose of Jesus’ return is to provide mankind with good government.
Jesus will bring good government to mankind
In what form does Christ return? He was resurrected as an invisible spirit person. (1 Peter 3:18) Then, he went to heaven and sat at God’s right hand. (Psalm 110:1) Much later, Jesus was brought before Jehovah God, “the Ancient of Days,” who granted Jesus power to rule over mankind. So Jesus returns, not as a human, but as an invisible King.
When Jesus arrives invisibly with his angels, he will judge mankind. He will destroy wicked people but grant everlasting life to those who accept him as King.
Jesus’ rule as King will transform the earth into a paradise. He will resurrect the dead so that they can enjoy life in that earthly Paradise.
