The belief in Jesus Christ will not automatically get anyone to heaven. Matthew 7:21 – Jesus said, Not everyone that saith unto me, Lord, Lord, shall enter into the kingdom of heaven; but he that doeth the will of my Father which is in heaven.
The only way a person can do the will of God is through the guidance of the Holy Spirit in the heart of man. Those who have the Holy Spirit in their heart have access to the kingdom of heaven. The belief in Jesus Christ alone can not get someone to heaven.
