The Holy Injil
Knowledge of the holy Injil is essential for anyone who wishes to understand the plan of Allah for mankind. In its pages we learn how to receive Allah's forgiveness of our sins. The word Injil was borrowed from the Greek language via the Syriac language. The original Greek word is euangel and means "good news." This describes the essence of the Injil. The Injil is a message of good news--good news of the forgiveness of sins! Sometimes the Injil is called the Gospel. Gospel is simply an old English word which also means "good news," like Injil.
The main character of the holy Injil is Prophet 'Isa Ibn Maryam. He is al-Masih (the Messiah), and the only one in all of Al-Kitab who is called by that title. It refers to the one chosen by Allah to be the leader and forgiver of his people. There are many prophets and messengers, but only one Masih. Furthermore, al-Masih is greater than all the prophets and apostles. This is why Prophet Yahya (pbuh) said, "After me comes he who is mightier than I, the thong of whose sandals I am not worthy to stoop down and loosen" (Mark 1:7).
It was 'Isa al-Masih who brought the Injil, the good news of Allah's forgiveness. He proclaimed it wherever he went and then passed it on to his 12 chosen companions, whom he called apostles. He told them to tell it to all mankind, as it is written, "'Isa said to them, 'Go into all the world, and preach the Injil to the whole creation" (Mark 16:15). After 'Isa al-Masih returned to heaven, his chosen apostles began to proclaim the message of the Injil wherever they went, and so did those who believed their word. This work of proclaiming the Injil to the whole world continues on to this present day.
