Jesus said He was the only way to heaven
John 14:6 “Jesus answered, ‘I am the way and the truth and the life. No one comes to the Father except through me.’”
John 11:25 “Jesus said to her, ‘I am the resurrection and the life. He who believes in me will live, even though he dies.’”
While there are many religious and spiritual teachers who claim that they can point you to heaven’s path, they themselves do not claim that they are that path. But, Jesus promised that He was the way to eternal life in heaven. This also proves that Jesus was/is God because since heaven belongs to God, it is God alone who determines who will live with Him forever there. And, Jesus’ ability to give spiritual life after physical death to those who believe in Him is further evidence that He was/is God who rules over heaven and our eternity.
