What should I call you snake? So uncomfortable to call you snake cause Islam never teach us to call someone with something thats not sounds nice and have a bad meaning . The teaching in Islam is so high and cant be matched by another religion. Cause Islam revealed for the humankind, forbid eachother to do sins, guilts and violence and tells eachother to do good things that can bring us to the peacefull happily life.If you feel Islam more comfortable, then everyone also have this feeling in their heart. Cause everyone have this fitroh (the basic purely natural genuine standard inscticnt that Allah give us into our heart) in each of them.Just like when you feel so so sad, heavy and when youre facing a lot of problems, then your fitroh will told to raise your face up to the sky, why? Cause there where our God position. He said in Quran His place is on the sky, so so high above the seventh sky and He is istiwa' fis sama'.Thats why when our heart feel heavy and sad, then our hearts will bring our face to look above just like we are trying to tell Him what we feel. And also when the animals feels thirsty cause there are no rainfall, they will also look above as if theyre begging so God with give them rain, its some of the signs that our God position is on the sky and this is what our prophet Muhammad -peace be upon Him- told in one hadits. Once he ever asked one little female slave, "where is Allah?" Then the slave told Him that Allah fis samaa'(on the sky), then the prophet told his friend (Utsman bin Maz'un ra), "free this girl cause shes muslimah". So my friend, this is your fitroh to choose Islam cause basically youre muslim since you have been bornth into this world. Rasulullah Muhammad said "All babies bornth as muslim, then their parents turn them into christian, jews and majusy". But the fitroh is in you my friend, and I hope its hidayah from Allah so you can hold Islam strongly in the future. And its also because Islams teaching is fit to every people on this world, Islam is the only teaching which make sense, and so easy to understand with our intelegency,Allah says in Quran :" Ta-Ha, We have not revealed unto thee (Muhammad) this Qur'an that thou shouldst be distressed, But only as an admonition to those who fear (Allah),A revelation from Him Who created the earth and the heavens on high. (Allah) Most Gracious is firmly established on the throne (of authority).(QS. Ta Ha 1-5). And no religion can match the teaching and the miracle of the Qur'an and nothing can make something as glorious as Quran, Allah says:"And if ye are in doubt as to what We have revealed from time to time to Our servant, then produce a Sura like thereunto; and call your witnesses or helpers (If there are any) besides Allah, if your (doubts) are true."(Al Baqoroh 23).And if you try comparing the Quran with bible, then the bible is a long way behind. You will find a lot of contradictions in bible that no prieches in every churchs on this world can explain and make us satisfied, but you wont find something like these contradictions in Quran.And about your question, can Islam and Christian co-exist? Then we should say that its our destiny to accept that. If the question is "can we"? Then Islam says in Quran and sunnah, we cant. Cause Allah says He only accept Islam as the right religion, and Allah must be worshipped and we may not have another God to be worshipped, Quran said:"Say: He is Allah, the One and Only; Allah, the Eternal, Absolute; He begetteth not, nor is He begotten; And there is none like unto Him." (Al Ikhlas, 1-4). So beside Islam then they will go forever to hell. But Now, since its our destiny that not every people on this earth open their heart to Islam, and we have to life side by side with the christian and other religions, then our prophet teach us to life peacefully with them as long they dont attacking, disturbing muslims. And in Muslims country, Christian and other religion ahlulkitab MAY NOT be not disturbed. Cause theyre under the agreement with the government, and our prophet Muhammad -shalallahu alaihi wasallam- said "whoever kill ahlul kitab(christian and jews) that have agreements with the government, then they will not enter the heaven". So the christian can life peacefully with muslim as long they respect eachother. And if they life in muslims country then their wealth, their blood, their family should be protected by the citizen and the government and may not be disturbed. This is the beauty of Islam, which have a high morality to humankind and bringing the human to only worship Allah cause He is the only God and He is the only one who deserved to be worshipped.
