Yes, I agree. These verses revealed about Christians.
"(5:83) And when they hear what has been revealed to the Messenger you see that their eyes overflow with tears because of the Truth that they recognize and they say: 'Our Lord! We do believe; write us down, therefore, with those who bear witness (to the Truth).
(5:84) And why should we not believe in Allah and the Truth which has come down to us when we do fervently desire that our Lord include us among the righteous?'
(5:85) So Allah rewarded them for these words with Gardens beneath which rivers flow so that they would abide there for ever. Such is the reward of the people who do good.
(5:86) Those who disbelieved and gave the lie to Our signs are rightfully the inmates of the Blazing Flame."
Also these verses
"(28:52) Those on whom We bestowed the Book before do believe in this (to wit, the Qur'an).
(28:53) When it is recited to them they say: "We believe in it for it is the Truth from our Lord. Indeed we were already Muslims."
(28:54) These will be granted their reward twice over because they remained steadfast; they repel evil with good, and spend (in alms) out of the sustenance We provided them,
(28:55) and when they hear any vain talk, they turn away from it, saying: "We have our deeds and you have your deeds. Peace be to you. We do not desire to act like the ignorant."
