Q: Can other religions lead to Heaven too?
A: No. Jesus said there is only one way, and that way is not a religion, not even Christianity. That way is Jesus Himself. People who think other religions lead to the same place forget that everyone does not even want to go to the same place. For example, many Hindus desire to rejoin an eternal life, die for the last time, lose their individuality, and be absorbed in a cosmic consciousness. Buddhists want to go to Nirvana, where among other thing, there is no love or joy. Muslims refuse to worship Jesus and are taught to fight against Christians. Either this pleases God or it displeases God, but it cannot be both. Everyone does not all worship the same God, because God does not have multiple personality disorder! In addition to all the verses referenced in the first question, there are five main things Scripture teaches about Jesus being the only way.
a) Only One Way: Imagine, before Jesus' terrible torture and crucifixion, Jesus praying in the Garden in Gethsemane saying "Father, if it be possible, let this cup pass from me", and God the Father saying, "Your dying on the cross is not needed to take away people's sins, we're just going through all this for fun." Jesus' death did not provide an "alternative way" to go to Heaven. Jesus is the one and only way.
b) Narrow is the gate and way that leads to eternal life (Matthew 7:14). Can someone like a Buddhist ever go to Heaven? Sure, because my father-in-law and mother-in-law were Buddhists, before they rejected Buddhism and came to Christ. A Muslim who wants to come to Christ has to realize that when Mohammed fought against Christianity, he was against the Triune God of Christianity.
c) Sacrifices a person sincerely might make to idols, are sacrifices to demons, not God. (1 Corinthians 10:19-20; Deuteronomy 32:16-17). C.S. Lewis wrote otherwise near the end of his book, The Lion, The Witch, and the Wardrobe. C.S. Lewis was wrong here.
d) However, God desires that none perish (2 Peter 3:9; Ezekiel 18:23,32). The narrowness is not due to God's lack of love, or withholding information, but due to people's rejection of God (Romans 1:18-21) and not combining what they know with faith (Hebrews 4:2).
e) Everyone who trusts in Jesus will never be put to shame (Romans 10:11b)
f) People have to call on one whom they believe, whom they have heard about, who have been preached to. (Romans 10:14-15)
An illustration might help here. Suppose you were on an island and you were warned that a hurricane was coming. There is a narrow bridge connecting the island to the mainland. It really does not matter which road you take on the island, or which way you go, as long as you do not want to leave the island. If you want to escape the hurricane though, you have to cross the bridge to the mainland. Now the typhoon of judgment for mankind’s sin in coming to our island called earth. God invites us all to cross the bridge He has provided for us and escape. If we choose not to cross God’s bridge though, then our destruction is our own fault.
When Helen Keller, who was blind and deaf, learned to communicate with the outside world, her teacher shared with her about God. Helen said that she always knew He was there, but she just did not know His name.
Contrary view: Pope John Paul II and many liberal Protestants believe that many religions lead people to the same God, that Jesus is the best way, but not the only way. Jesus said, "no one comes to the Father, but through Me." (John 14:6). If you are going to the same place as all the other religions lead, or you can go to a different place, where Jesus leads.
