We ALL are children of Adam and Eve and we ALL are Cousin Brothers & Sisters

True Friends are not those who come to eat only but run away during your bad times. Rather, true friends are those who sincerely help you and accompany you, doing good deeds with and for you, for your eternal (infinite, future) life as well.

You will certainly find the nearest in love (friendship) to those who believe (to be) those who say: We are Christians; this is because there are priests and monks among them and because they do not behave proudly. (Ref:Al_Quraan_005.082)

The world has enough negativity and it is time to tell the truth to the world to unite as a Global Family and Pray for each other:

O people! be careful of (your duty to) your Lord, Who created you from a single being and created its mate of the same (kind) and spread from these two, many men and women; and be careful of (your duty to) Allah, by Whom you demand one of another (your rights), and (to) the ties of relationship; surely Allah ever watches over you. (Al_quraan_004:001)

Allah Sent Prophets and Messengers as his Love to Humanity all over the World:

(All) people are a single nation; so Allah raised prophets as bearers of good news and as warners.  (Ref:Al_Quraan_002.213)
And every nation had a messenger. (Ref:Al_Quraan_010.047)
And We have not sent you (Muhammad) but as a mercy to the worlds. (Al_Quraan_021.107)

We should build a Bridge between different Beliefs:

Allah told us to come to the Common Points FIRST. (Ref:Al_Quraan_003:064)

Key to World Unity could be in Sharing Food and Joining in Marital Relations:

This day (all) the good (Halaal) things are lawful unto you; and the (Halaal) food of the People of the Book is lawful unto you and your food is lawful unto them; and Lawful unto you in marriage are the chaste women from the believers and the chaste women among the People of the Book (including True Jews or Christens Believer Women); when you have given them their dowries (Mahr), taking (them) in marriage, not fornicating nor taking them for paramours in secret; and whoever denies faith, his work indeed is of no account, and in the hereafter he shall be one of the losers. (Al_Quraan_005.005)

Remember: There is NO Compulsion in Religion. (Ref:Al_Quraan_002:256)
