Orthodox Christianity teaches one must accept Jesus to be saved. Few Christians can explain what exactly one “saved” from. Rather than to discuss what “saved” means, what does it mean to accept Jesus or to believe in Jesus? Jesus died about 2000 years ago. He is not here to speak for himself. The only available means a person in the 21st century has to hear about Jesus is by the testimony of others. This testimony is transmitted either by word of mouth, a minister or pastor, books, radio, internet, etc. None of these sources had contact with Jesus. Using the Bible as the primary source opens more questions. There is no agreement among the churches on the interpretation on Christian scripture. If there were there wouldn’t be so many churches. Then the problem of authenticity of the Bible comes up. The New Testament is a collection of 27 books. The early church fathers chose what books are in and what books are out. How can we trust their decision? Who were these men? Then the problem of authorship of these 27 books comes up. Many of the authors of these books are anonymous. Scholars are not in agreement on who wrote them. Then there is the problem of the authenticity of the subject matter itself. We can’t ask the authors because they are long dead and we don’t know who they are anyway. Added to the mix are other books that didn’t make the cut. How can anyone know the Gospel of Thomas is is not authentic? Not only is Christianity diverse but there are many other religions across the planet. It would seem Christianity is a crapshoot, a gamble.
Hazrat Mirza Ghulam Ahmad 1835-1908, the Promised Messiah and Mahdi, the Imam of the age and the Founder of the Ahmadiyya Movement in Islam, was perfectly true when he prophesied about this scenaio:
"Harken, all ye people. This is a prophecy of Him Who had created heaven and earth. He will spread this Community of His in all countries and will make it supreme over all, through reason and arguments. The days are coming, indeed they are near, when this will be the only religion which will be held in honor. God will bestow extraordinary blessings on this religion and Movement. He will frustrate everyone who seeks to destroy it. This supremacy will last till the Judgement Day.
Remember, that no one will descend from heaven. All our opponents who are alive today will die and no one will see Jesus son of Mary descending from heaven. Then their next generation will pass away and no one of them will see this spectacle. Then the generation next after that will pass away without seeing the son of Mary descending from heaven. Then God will make them anxious that though the time of the supremacy of the cross had passed away and the world had undergone great changes, yet the son of Mary had not descended from heaven. Then the wise people will suddenly discard this belief. The third century after today will not yet have come to a close when those who hold this belief, whether Muslims or Christians, will lose all hope and will give up this belief in disgust. There will then be only one religion that will prevail in the world and only one leader. I have come only to sow the seed, which has been sown by my hand. Now it will sprout and grow and flourish and no one can arrest its growth."
