Dear Muslims, I have a sincere question about the nature of God using my own common sense..?

Dear,God did this just to save Jesus (PBUH) and also to send him back when needed.He could have done in front of them but he did because then they have more strongly believed that Jesus (PBUH) is God and also then Judaism had been finished completely.I think Mr. Khan is also right and Quran is not its opposite but parallel.It this wouldn't have been done that the world wouldn't have been same.
