'Heaven' in the Bible

[born anew] into an inheritance which is imperishable [beyond the reach of change] and undefiled and unfading, reserved in heaven for you,

It was revealed to them that their services [their prophecies regarding grace] were not [meant] for themselves and their time, but for you, in these things [the death, resurrection, and glorification of Jesus Christ] which have now been told to you by those who preached the gospel to you by the [power of the] Holy Spirit [who was] sent from heaven. Into these things even the angels long to look.

who has gone into heaven and is at the right hand of God [that is, the place of honor and authority], with [all] angels and authorities and powers made subservient to Him.
