Heaven is the place which God lives and his glory is present in heaven, only the righteous is allow to enter heaven. The Bible also teaches that faithful servants of God who have died in faith are with Him. Jesus spoke of a future gathering of God's people, giving believers hope of eternal life in His presence.
According to what I study in the bible that Enoch and Elijah are in heaven. Others point to the resurrection and ascension of Jesus Christ as the assurance that believers who belong to Him will ultimately share in heavenly glory.
