(2.) Meaning of words in the original,
(c) Hebrews galgal, literally a "wheel," is rendered "heaven" in Psalm 77:18 (R.V., "whirlwind").

(a) Christ calls it his "Father's house" (John 14:2).
(e) The "eternal kingdom" (2 Peter 1:11).
(g) The "better country" (Hebrews 11:14, 16).
(h) The blessed are said to "sit down with Abraham, Isaac, and Jacob," and to be "in Abraham's bosom" (Luke 16:22; Matthew 8:11); to "reign with Christ" (2 Timothy 2:12); and to enjoy "rest" (Hebrews 4:10, 11).
In heaven the blessedness of the righteous consists in the possession of "life everlasting," "an eternal weight of glory" (2 Corinthians 4:17), an exemption from all sufferings for ever, a deliverance from all evils (2 Corinthians 5:1, 2) and from the society of the wicked (2 Timothy 4:18), bliss without termination, the "fulness of joy" for ever (Luke 20:36; 2 Corinthians 4:16, 18; 1 Peter 1:4; 5:10; 1 John 3:2). The believer's heaven is not only a state of everlasting blessedness, but also a "place", a place "prepared" for them (John 14:2).
