I AM THE WAY, THE TRUTH, AND THE LIFE, NO ONE ENTERS THROUGH HEAVEN BUT THROUGH ME.
Jesus, and the Bible says many times over and over, that Jesus Christ, the Messiah the Savior, God in the flesh, is the ONLY way to heaven, and only the people that would be born again, in the Spirit of God, through Jesus' sacrifice, will be saved from everlasting judgment.
Jesus tells us to enter through the narrow gate, for that is the way to eternal life.
But much of the modern world is full of Liberalism: which is a dogma of "Progress", and "open-mindedness". I am sorry to say, but if you are not born again in the Spirit of God, through Jesus Christ, then you are not going to Heaven. Liberals may like to call us "closed-minded", then fine. I'm closed-minded on the truth, and you are open-minded to a sea of falsehoods, with one tiny drop of truth.
But the only path to rightousness, is through the one tiny drop of truth.
This is the only God that has sacrificed Himself for the sins of the world, the only One who made thousands of bold prophecies in His Holy Book with 100% accuracy. He is the only One to give a detailed account of the Creation of the world (with geneologies, ages, deaths), the only One who made the world out of Love. This God professed Himself to be the greatest, all mighty, supreme, and ONLY God. He knows of none other gods.
Please, follow the truth. "For you will know the truth, and the truth shall set you free".
