Isaiah 7:14 Therefore the Lord himself shall give you a sign; Behold, a virgin shall conceive, and bear a son, and shall call his name Immanuel.
Immanuel - from im and el (with us is God)
For unto us a child is born, unto us a son is given: and the government shall be upon his shoulder: and his name shall be called Wonderful, Counseller, The mighty God, The everlasting Father, The Prince of Peace.
Daniel 7:13 I saw in the night visions, and, behold, one like the Son of man came with the clouds of heaven, and came to the Ancient of days, and they brought him near before him. 14 And there was given him dominion, and glory, and a kingdom, that all people, nations, and languages, should serve him: his dominion is an everlasting dominion, which shall not pass away, and his kingdom that which shall not be destroyed.
Then Jesus identified himself as that “son of man” who would be “coming in the clouds of heaven”.
Mark 14:62 And Jesus said, I am: and ye shall see the Son of man sitting on the right hand of power, and coming in the clouds of heaven.
Those who deny that Jesus was truly God and truly man deny what both the Old and the New Testaments say. Jesus said that those who denied His words will be judged on the last day.
John 12:48 He that rejecteth me, and receiveth not my words, hath one that judgeth him: the word that I have spoken, the same shall judge him in the last day.
Unless you understand that Jesus was truly man and speaking as a man at times and that He was also truly God you cannot you will be judged with those who denied His words.
