Trust this for a moment. Jesus is as present as He was before the conjectures of a Galilean ascension in Acts 1:11. The confusion rests in not knowing the difference between the Son of Man and the Son of the living God. A person guided by the truth knows that Jesus used two methods of communication when He was on earth. To those of this world, Jesus communicated in parables. This kept his messages clouded in mysteries so that ordinary people could not figure out the realities of God’s Kingdom.
The disciples came to him and asked, “Why do you speak to the people in parables?” He replied, “The knowledge of the secrets of the kingdom of heaven has been given to you, but not to them. Whoever has will be given more, and he will have an abundance. Whoever does not have, even what he has will be taken from him. This is why I speak to them in parables: “Though seeing, they do not see; though hearing, they do not hear or understand.
“In them is fulfilled the prophecy of Isaiah: ‘You will be ever hearing but never understanding; you will be ever seeing but never perceiving. For this people’s heart has become calloused; they hardly hear with their ears, and they have closed their eyes. Otherwise, they might see with their eyes, hear with their ears, understand with their hearts and turn, and I would heal them.’ But blessed are your eyes because they see, and your ears because they hear” (Matthew 13:10-16 NIV).
The man betrayed by a kiss was not the Son of God, but the Son of Man who would be ridiculed, and spat at by evil men at the cross. As the Son of Man, Jesus came to serve humanity and not to be served by humanity (Matthew 20:28). A servant and a Master should be regarded as directly opposed to each other. The Son of Man is different from the Son of God, who is Spiritual in nature. The Son of God could not be ridiculed and spate at, without inviting the sin of blasphemy.
“And so I tell you, every sin and blasphemy will be forgiven men, but the blasphemy against the Spirit will not be forgiven. Anyone who speaks a word against the Son of Man will be forgiven, but anyone who speaks against the Holy Spirit will not be forgiven, either in this age or in the age to come” (Matthew 12:31-32 NIV).
The significance of the above Scripture is that the Son of Man is as weak as human beings are weakly. However, the Son of God is Spiritual. The Jews succeeded in killing Jesus, who they treated as the Son of Man. They could not have done that, had they known that He was Christ, Son of the Living God. That would have invited the curse implied for blasphemy.
“If you are the Christ,” they said, “tell us” Jesus answered, “If I tell you, you will not believe me, and if I asked you, you would not answer. But from now on, the Son of Man will be seated at the right hand of the mighty God.” They all asked, “Are you then the Son of God?” He replied, “You are right in saying I am.” Then they said “Why do we need any more testimony? We have heard it from his own lips” (Luke 22:67-71).
As far as the Jews were concerned, they did not kill the Son of God, but they killed the Son of Man. Jesus was accused of blasphemy, for which, according to Jewish laws, such a person deserved death. Jesus was also clear about that reality; hence, He did not oppose the process of his murder. The Son of Man had to die, for humanity to access redemption.
