Believe in Jesus as islam says and u have to believe in One God Allah, and the Last messenger Prophet Mohammed ( Pbuh ), This is the basic criteria to enter Heavens.
“They have certainly disbelieved who say, ‘God is the Messiah, the son of Mary’ while the Messiah has said, ‘O Children of Israel, worship God, my Lord and your Lord...’” (Quran 5:72)
“They have certainly disbelieved who say, ‘God is the third of three.’ (Rather) there is none worthy of worship except One (God). And if they do not desist from what they are saying, there will surely afflict the disbelievers among them a painful punishment. So will they not repent to God and seek His forgiveness? And God is Forgiving and Merciful. The Messiah (Jesus), son of Mary, was no more than a Messenger before whom many Messengers have passed away; and his mother adhered wholly to truthfulness, and they both ate food (as other mortals do). See how We make Our signs clear to them; and see where they are turning away!” (Quran 5:73-75)
And also:
“O People of the Book (Jews and Christians)! Do not exceed the limits in your religion, and attribute to God nothing except the truth. The Messiah, Jesus, son of Mary, was only a Messenger of God, and His command that He conveyed unto Mary, and a spirit from Him. So believe in God and in His Messengers, and do not say: ‘God is a Trinity.’ Give up this assertion; it would be better for you. For God is indeed (the only) One God. Far be it from His glory that He should have a son. To Him belongs all that is in the heavens and in the earth. And God is sufficient for a guardian.” (Quran 4:171)
“And they say: ‘The Most Merciful (God) has taken (for Himself) a son.’ Assuredly you utter a hideous thing, whereby almost the heavens are torn, and the earth is split asunder and the mountains fall in ruins; That they ascribe unto the Most Merciful a son, when it is not suitable for (the Majesty of) the Most Merciful that He should take a son. There is none in the heavens and the earth but comes unto the Most Merciful as a slave.” (Quran 19:88-93)
“And (beware the Day) when God will say, “O Jesus, Son of Mary, did you say to the people, ‘Take me and my mother as deities besides God?’” He will say, ‘Exalted are You! It was not for me to say that to which I have no right. If I had said it, You would have known it. You know what is within myself, and I do not know what is within Yourself. Indeed, it is You who is Knower of the unseen. I said not to them except what you commanded me – to worship God, my Lord and your Lord…’” (Quran 5:116-117)
“And I did not create the jinn and mankind except to worship Me.” (Quran 51:56)
“And We certainly sent into every nation a messenger, (saying), ‘Worship God and avoid all false objects of worship…’” (Quran 16:36)
“And (remember) when Jesus, son of Mary, said: ‘O Children of Israel, I am the Messenger of God sent to you, confirming the Torah (which came) before me...’” (Quran 61:6)
Jesus Christ, the son of Mary, was the last in the line of Jewish prophets. He lived according to the Torah, the Law of Moses, and taught his followers to do likewise. In Matthew 5:17-18, Jesus stated:
“Think not that I have come to abolish the law and the (way of) the prophets; I have come not to abolish them but to fulfill them.”
Not only did Jesus affirm the scriptures revealed before him, but he also foretold of another prophet to come after him. God says:
“And when Jesus, son of Mary, said: ‘O Children of Israel! Indeed I am the messenger of God unto you, confirming that which was (revealed) before me in the Torah, and bringing good tidings of a messenger who will come after me, whose name is the Praised One.’” (Quran 61:6)
This fact is also mentioned in the New Testament. Careful study shows that Jesus, peace be upon him, refers to the same prophet in John 14:16-17:
“And I will give you another Counselor (the Prophet Muhammad, may the mercy and blessings of God be upon him), to be with you forever, even the Spirit of Truth.”
So the Only way is ISLAM
