Jesus said:
Matthew 10:34-39
"Do not think that I came to bring peace on earth. I did not come to bring peace but a sword. 35 For I have come to 'set a man against his father, a daughter against her mother, and a daughter-in-law against her mother-in-law'; 36 and 'a man's enemies will be those of his own household.' 37 He who loves father or mother more than Me is not worthy of Me. And he who loves son or daughter more than Me is not worthy of Me. 38 And he who does not take his cross and follow after Me is not worthy of Me. 39 He who finds his life will lose it, and he who loses his life for My sake will find it.
NKJV
When Jesus returns it will be as a conquering King who will destroy Israel's enemies, all false religions, and to inaugurate the Kingdom of God on earth.
Revelation 19:11-16
Now I saw heaven opened, and behold, a white horse. And He who sat on him was called Faithful and True, and in righteousness He judges and makes war. 12 His eyes were like a flame of fire, and on His head were many crowns. He had a name written that no one knew except Himself. 13 He was clothed with a robe dipped in blood, and His name is called The Word of God. 14 And the armies in heaven, clothed in fine linen, white and clean, followed Him on white horses. 15 Now out of His mouth goes a sharp sword, that with it He should strike the nations. And He Himself will rule them with a rod of iron. He Himself treads the winepress of the fierceness and wrath of Almighty God. 16 And He has on His robe and on His thigh a name written:
KING OF KINGS AND LORD OF LORDS.

As to the Qur'an's myth concerning Mary that is all it is, a myth. Mary was betrothed to Joseph when she became pregnant with the Son of God. Joseph honored God by believing God and honoring his commitment to marry Mary even though she was carrying God's son. A lot of what the Qur'an tells you about Mary was plagiarized from the Protoevangelium of James, which is also known as the Infancy Gospel of James.
