If Muslims and Jews believe in God, then why won’t they go Heaven? Surely we all believe in the same God but call Him different names?
Jesus said: "I am the Way, the Truth and the Life; No one comes to the Father except through Me" John 14:6. Either He was deluded, or a deceiver, or He meant what He said – there is only one God and one way to the Father. If there were another way to Heaven, the death and resurrection of Christ would be superfluous and unnecessary.
Our God is not schizophrenic – using different names to propagate different belief systems. His Word is: "For there is only one God and one Mediator who can reconcile God and people .. Christ Jesus. He gave His life to purchase freedom for everyone. This is the message that God gave to the world at the proper time." 1 Tim 2:6 NLT. In Noah’s day, the ark was the only means of salvation. Christ is God’s Ark for the "whosoever will" believe, regardless of their faith or creed.
