Jesus did amazing miracles and preached great wisdom; but who was He? (Mark 4:41; Luke 7:49).  That question refused to go away.   Every time Jesus spoke or acted with authority, He challenged the position of the religious leaders and made everybody wonder about His true identity (Matthew 7:29).  What He did was so compassionate and kind, so uniquely powerful; yet what He said was considered to be blasphemous because He claimed to have a uniquely intimate relationship with Father God (John 10:30) and allowed Himself to be worshipped as God (John 20:28-29).  

There were only three possible explanations: either Jesus was God as He claimed; or He was mentally unwell and deceived people; or He has special powers from Satan and therefore He was evil.  Mad, bad or God?  But the option of being a good teacher was excluded because He claimed to be 'one with the Father', and therefore God in a human body (Colossians 2:9).  So, some of the Jews decided that Jesus must be either demonised or mentally ill or both.  But their assessment was challenged by others who saw that His power was constructive whereas Satan's would always be destructive.  To think that Jesus was demonised or mad simply did not fit the facts.  

Jesus’ claim to be uniquely loved by Father God, because He was willing to be the atoning sacrifice for the sins of the world was extraordinary (John 1:29).  And to claim to be sacrificed and then have divine authority to be able to come alive again, is a human impossibility.  It was only possible if He was God (John 1:1-3).
 
The identity of Jesus continues to be a puzzle to many people.  He does not fit any known human category.  He is too powerful to be an ordinary man, and wiser than even the best teacher.  But His claim to be in control of human life - to be authorised by His Father to lay it down and then to take it up again - means He must be God ... and that was proved when He died and rose again (Romans 1:4).  The death and resurrection of Jesus is still the message of the Gospel, calling people from every culture and religious background to believe in the Man who is God (1 Timothy 2:5).  Wherever you work or live, it is the same gospel which is powerful to save all those who believe.  But they will not be able to believe unless they hear it (John 20:30-31); and that means you tell them!
