Revelation 21:7
He that overcometh shall inherit all things; and I will be his God, and he shall be my son. (Revelation 21:7)
His God … my son.
 Compare Gen. 17:7; 2 Sam. 7:14. The promise of intimate family connection is here set forth. The sinner saved by grace will be received into the family of God and be brought into a relation as close as if he had never sinned. The inhabitants of unfallen worlds cannot be closer to God and Christ than will be the redeemed sinner. See DA 25, 26.
All things.
Textual evidence attests (cf. p. 10) the reading “these things,” that is, the promises given in the Revelation, particularly the things mentioned in this chapter.
Overcometh.
 That is, according to the Greek, continually conquers, or habitually conquers. The Christian lives the victorious life by the power of the Holy Spirit. He may make mistakes (see on 1 John 2:1), but his normal life presents a picture of spiritual growth (cf. Rev. 2:7, 11, 17, 26; 3:5, 12, 21).
