New Defender's Study Bible Notes
14:2 my Father’s house. The Father’s “house” is where we shall dwell forever (Psalm 23:6). It is also “the household of God” (Ephesians 2:19) and corresponds to the “holy city” (Revelation 21:2) which will be placed on the new earth as our eternal home. Its dimensions are given (see note on Revelation 21:16), and it is amply large to provide many “mansions.” This word is used only one other time, in John 14:23, referring to the “abode” where the Father and the Son will also dwell with the believer.
14:2 a place. Thus heaven is a “place,” not merely a state of mind, or some sort of fifth dimension. It is a physical place in God’s eternal cosmos.
