Revelation 21:7 - Ellicott's Commentary On The Whole Bible

He that overcometh shall inherit all things... — Rather, He that conquereth shall inherit these things; and I will be to him God, and he shall be to me a son. The general promise of Revelation 21:3 is in part repeated, and this time more individually. Again we catch, as it were, the echo of the promises to the Seven Churches, the blessing is for him that conquereth. The idea of the war and the conquest is a favourite one with St. John. (John 16:33, and 1 John 2:13-14; 1 John 5:4-5; see also Note on Revelation 2:7.) The source and weapon of victory have been before stated: the blood of the Lamb, the word of their testimony (Revelation 12:11), and the victory of faith (1 John 5:4).
