It is different because God, as the Creator, is not just another human on the same level as a human bulling another of his fellow humans. God has no insecurity or need to bully others to lord it over others or feel superior, as human bullies do. God is Lord and is Superior . God sees everything and the motive of each person, in each situation and their actions and treatment of others, so that when He brings judgment it is always precisely fair, wise, appropriate for the situation, and meant to bring ultimate change and repentance from evil to good.
It would not be a surprise to me to find that we do not actually understand the purpose of Jesus (Isa PBUH). The Jews doubted that he was even here.
Perhaps he was here for God's benefit, to perhaps establish a closer connection to the difficult to understand 'man'. John 5:30-47 is a whole sermon in itself and to me underlines the modern lack of understanding of God and of the Christ he sent:
I can of mine own self do nothing: as I hear, I judge: and my judgment is just; because I seek not mine own will, but the will of the Father which hath sent me.
31 If I bear witness of myself, my witness is not true.
32 There is another that beareth witness of me; and I know that the witness which he witnesseth of me is true.
33 Ye sent unto John, and he bare witness unto the truth.
34 But I receive not testimony from man: but these things I say, that ye might be saved.
35 He was a burning and a shining light: and ye were willing for a season to rejoice in his light.
36 But I have greater witness than that of John: for the works which the Father hath given me to finish, the same works that I do, bear witness of me, that the Father hath sent me.
37 And the Father himself, which hath sent me, hath borne witness of me. Ye have neither heard his voice at any time, nor seen his shape.
38 And ye have not his word abiding in you: for whom he hath sent, him ye believe not.
39 Search the scriptures; for in them ye think ye have eternal life: and they are they which testify of me.
40 And ye will not come to me, that ye might have life.
41 I receive not honour from men.
42 But I know you, that ye have not the love of God in you.
43 I am come in my Father's name, and ye receive me not: if another shall come in his own name, him ye will receive.
44 How can ye believe, which receive honour one of another, and seek not the honour that cometh from God only?
45 Do not think that I will accuse you to the Father: there is one that accuseth you, even Moses, in whom ye trust.
46 For had ye believed Moses, ye would have believed me; for he wrote of me.
47 But if ye believe not his writings, how shall ye believe my words?
The 4th Surah of the Quran echoes many of the things that Jesus (Isa PBUH) said, but the shaitan has placed a wedge of lack of understanding and hatred between men, and that will remain until he returns.
