There had been a tendency, and it may have crept into the churches, to worship angels. The worship status of angels has therefore been utterly refuted in the first chapter, and the great superiority of Christ, the eternal Son of God has been established.
The writer adds these words: ’whereof we speak’, and the question is asked, ‘Where has he been speaking about heaven and the world to come up to this point?’ Probably it begins in chapter 1, verse 2: ‘[God] hath in these last days spoken unto us by his Son’, and he is referring to what was begun to be taught by Christ himself. The New Testament is pre-eminently the Testament of eternity. Eternity is in the Old Testament also, but it's more particularly emphasised in the New Testament. ‘Whom he hath appointed heir of all things’ – that also is about the world to come. Then in verse 3 of chapter 1: ‘Who being the brightness of his glory, and the express image of his person, and upholding all things by the word of his power, when he had by himself purged our sins, sat down on the right hand of the Majesty on high.’ That is introducing the world to come: the place of Majesty on high, to which the people of God are moving. Verse 8 in chapter 1 refers to the Christ’s kingdom: ‘Thy throne O God is for ever and ever. A sceptre of righteousness is the sceptre of thy kingdom.’ That kingdom began to be established in the hearts of believers through the preaching of the gospel, but it will come in visible form in the age to come. ‘How shall we escape’, he asks in chapter 2, verse 3, ‘if we neglect so great salvation?’ This salvation is not complete with conversion, but leads to the resurrection of the body, and the eternal glory (Hebrews 2:10, verse 10). It is about the world to come. We are partakers of the heavenly glory (Hebrews 3:1), the ultimate vocation and the goal: heaven, the world to come.
