1) We all want to be respected and yet be told when the bridge is broken even when we plan to cross it for the dream vacation. 2) Have you read the Bible? It is a fact of life that we will all die unless raptured first. Only in Jesus God came in the flesh, died, and rose again. Christianity is unique because Jesus takes away the sins of the world. He already put the ticket to His Home the Heaven in everyone's hand. All it takes to leave Hell behind is to accept Him. Salvation is a gift of God, by Grace, and cannot be earned. 3) Yes, know the real purpose of the Bible and you will find that Jesus is the only salvation now that He has come.
Have you carefully read the Bible, Quran, Analects of Confucius & DaoDeJing, and Vedas/Upanishads? If you do, you will find out that all roads of salvation lead to Jesus. Magi of Eastern religions worshiped Jesus. Jesus Himself proclaims that He has religious followers not of Judaism that He is bringing together (John 10:16). Jesus vision is “On earth peace, goodwill toward men” (Luke 2:14, NKJV).
Confucius worshiped Dao (the Way), also known as ShangDi. The ancient character ShangDi symbolizes God on a tree, as can be seen in the cover pages of “God’s Promise To The Chinese” and “Highway To Your Immortality.” Buddha Gautama worshiped Dhamma (the Truth) as in the scripture Dhamma-pada. "Only those who live under Dhamma will reach the place beyond death" (Dhamma-pada VI:86). While there are many Buddha’s, there is only one Supreme Buddha, Dhamma Himself. Jesus is the only person proclaiming Himself as Dhamma and Dao (John 14:6).
According to Hindu scriptures, “The only way to immortality is to know Purusa. There is no other way to immortality” (Svetasvatara Upanisad 3:8, Yajur Veda 31:18). Purusa means the Person in English. Purusa is the Supreme God Prajapati, who created the universe and yet was sacrificed (Rg Veda 10:90:6, Svetasvatara Upanisad 3:11-12, 15, 4:2, Mundaka Upanisad 1:2). Jesus is God In Person.
The Quran proclaims that salvation is only through the Grace of God (Rahmanullah or Allah Ar-Rahman). “None shall have the power of intercession, but such a one as has received permission (or promise) from Ar-Rahman” (Quran 19:87). See also 17:110 25:59-60, 20:108-109, 19:18-21. The Quran calls out Ar-Rahman most in Quran chapter 19 titled “Mary” the mother of Jesus.
The Bible proclaims that we are saved by Rahman (Grace) through Jesus, not by our own works but as a gift, and transformed by Rahim (Mercy) through the Holy Spirit (Titus 3:4-8 NKJV, Eph 2:7-8). Truth and Rahman came through Jesus (John 1:17). Jesus is Ar-Rahman, and the Holy Spirit is Ar-Rahim. The Quran agrees with the Bible that intercession or salvation comes only through Jesus Ar-Rahman. We pray in the name of one Allah: the Father, the Most Gracious Son Jesus, and the Most Merciful Holy Spirit. Thus, according to the Quran and the Bible, salvation is only through Jesus.
Historically “This formula – Bimillahi rrahmani rraheem – is of Jewish origin. It was in the first instance taught to the Koreish by Omayah of Taief the poet (one of the Hanyfs, Sprenger, i.76) who was a contemporary with, but somewhat older than, Muhammad, and who, during his mercantile journeys into Arabia Petraea and Syria, had made himself acquainted with the sacred books and doctrines of Jews and Christians (Kitab al-Aghani, 16, Delhi). Muhammad adopted and constantly used it, and it is prefixed to each Sura except the ninth” (1876 J.M.Rodwell “The Koran”). Syriac Christians at the time of Muhammad called Jesus as Rahmana (1902 H. Hirschfeld “New Researches into the Composition and Exegesis of the Quran).
Thus, if all these religions really teach the scriptures instead of against the scriptures, followers will come to Jesus. To focus on China, read Ethel Nelson's book. Don Richardson's "Eternity In Their Hearts" shows how native religions of the world point to Jesus. Always verify the verses yourself.
