Are there more than one way to God? Do all religions lead to the same God?
No, the Bible says that Jesus is the only way to God.
"Jesus said to him, "I am the way, the truth, and the life. No one comes to the Father except through Me." (John 14:6)
"He who believes in the Son has everlasting life; and he who does not believe the Son shall not see life, but the wrath of God abides on him." (John 3:36)
"Let it be known to you all, and to all the people of Israel, that by the name of Jesus Christ of Nazareth, whom you crucified, whom God raised from the dead, by Him this man stands here before you whole. This is the "stone which was rejected by you builders, which has become the chief cornerstone.' Nor is there salvation in any other, for there is no other name under heaven given among men by which we must be saved." (Acts 4:10-12)
"He who has the Son has life; he who does not have the Son of God does not have life." (1 John 5:12)
