Although there are about 4200 religions in the whole world, the most popular one and the largest is Christianity. This religion has about 2.4 billion followers throughout the world. Although Christianity has so many branches and denominations, the three most common branches of Christianity are Catholicism, Orthodox, and Protestantism.
Christianity, as a religion, is based on the teaching of Jesus Christ. According to the followers of this religion, they believe Jesus Christ is the savior of the whole world and that he was sent to bring humankind back to God.
All the activities of Jesus Christ when he was on earth are contained in the Holy Bible. One of the core beliefs of Christianity is that God exists in trinity i.e., the father, the Son, and the Holy Spirit. As a result of this, Jesus Christ is usually referred to as the son of God. One of the reasons why Christianity is surging in popularity is because the followers of this religion have been instructed to spread the message of Jesus Christ to all parts of the world.
