CHRISTIANITY & JESUS
The message that was brought by the Messiah, Jesus, (peace be upon him) was the call to worship God, the One, the Lord of the Messiah and the Lord of the worlds:
“Now this is eternal life: that they may know you, the only true God, and Jesus Christ, whom you have sent”
(John 17:3 – NIV)
“A certain ruler asked him: ‘Good teacher, what must I do to inherit eternal life?’ ‘Why do you call me good?’ Jesus answered. ‘No one is good – except God alone.’” (Luke 18:18-19 – NIV)
“The devil led him up to a high place and showed him in an instant all the kingdoms of the world. And he said to him, ‘I will give you all their authority and splendour, for it has been given to me, and I can give it to anyone I want to. So if you worship me, it will all be yours.’ Jesus answered, ‘It is written: “Worship the Lord your God and serve him only.”’” (Luke 4:5-8 – NIV)
Believing in and worshipping Allaah alone, besides Whom there is no other god, is the greatest teaching brought by the Messiah, and it is the greatest teaching brought by all the Prophets.
Allaah says (interpretation of the meaning):
“And (remember) when Allaah will say (on the Day of Resurrection): ‘O ‘Eesa (Jesus), son of Maryam (Mary)! Did you say unto men: Worship me and my mother as two gods besides Allaah?’ He will say: ‘Glory be to You! It was not for me to say what I had no right (to say). Had I said such a thing, You would surely have known it. You know what is in my inner‑self though I do not know what is in Yours; truly, You, only You, are the All‑Knower of all that is hidden (and unseen).
