Christianity is the heavenly  religion before  the coming of is the religion of those who followed jesus peace be upon him .God revealed upon this prophets the gospel  .jesus foretold the coming of Muhammad  peace be upon him whose name was mentioned in the gospel.christianity was not for all mankind but for a specific category of people in a specific period of time .through time christianity got altered and twisted by humans as it was devided into three different faiths .there some who believe in  only God and others who believe that jesus is the son of God and others who believe that God is one of three this is called the triad. These people believe wrong because God is one no more he is the one who has no children and the one who wasn’t born or gave birth.
