The modern Christianity that has been going on in the world for many centuries is not the initial Christianity that was brought by the Prophet Jesus (PBUH). Now it consisted on a pretended and mixed faith, which St. Paul's was invented for his popularity. In the life of Hazrat Eesa bin Maryam (PBUH), Paul was his staunch opponent and he had never met him. After Jesus was taken up to heaven, this man suddenly began to sing in sympathy and harmony, and began to show excessive devotion to Jesus. In order to spread his beliefs widely, Paul made a mixture of the fanatical beliefs of the Greeks, Christians and Sun-worshipers and declared it to be true Christianity. The fact is that after Jesus (PBUH) his twelve disciples began to spread the teachings of Jesus (PBUH) on the planet with great zeal, and with great speed people began to abandon the outdated traditions of Judaism and started to join Christianity. The Jewish priests of that time were disturbed to see that their glory was in danger because of Christianity. To prevent this, St. Paul from Judaism announced that he had converted from Judaism to Christianity. And he gains the sympathy of other disciples by telling the story of Jesus descent upon himself. And he engages in the preaching of Christianity and shows such zeal that, he pushes the rest of the disciples into the background and even proclaims Prophecy in the name of revelation. He severely persecuted the followers of Christ in the enmity of Jesus and even martyred some. As a Jew, he used to go to his synagogue, a place of worship. Gradually he stopped going to Sina Gag too. He told his Christian followers that one day, fourteen years after Jesus, he came to him in a dream and demanded that he renounce violence against his followers. Paul said that after that incident his world changed and he repented of all his oppression. This article will provide a critical overview of St. Paul's personality in the light of the Bible and his impact in the modern Christianity.

The creation of the universe and maintaining it on a certain balance is called the nature of Allah Almighty. Allah has made the human being the trustee of this natural environment and has guided humanity in the basic principles of natural needs and purposes.

The Holy Prophet (PBUH) has laid down several principles for the survival of humanity and the fulfillment of its natural needs.

The study concludes that if one lives in the light of the principles and rules laid down by the Holy Prophet, the good life in this world can be achieved along with the eternal success of the hereafter. The research recommends the government, scholars and media to run a campaign for awareness about the environmental problems in their domains.
