Revelation 4:1

No sooner had St. John received in the preceding vision the documents he was to transmit to the seven Churches of Asia [Asia Minor], when, behold, a new scene displays itself. Heaven opens, and St. John is invited up thither by the voice which had spoken to him before, and is told he shall see what is to happen in future ages. On a sudden appears a throne, and the Almighty himself seated upon it. The rainbow which surrounds the throne, denotes the covenant of reconciliation and peace between God and man. (Walmesley) --- Behold a door open. Here begins what may be looked upon as a second part of the Apocalypse, and from hence to the two last Chapter s are contained wars and victories of the Church over all its enemies, the devil, Jews, heathens, and heretics. --- These visions are so differently expounded, when applied to different events, that this alone may convince us how uncertain are those various interpretations. The servants of God are taught that they must expect to meet with many trials, afflictions, and persecutions; but this ought to be a great subject of consolation to the faithful, that they are assured of victory if they fight manfully, and of a recompense of endless happiness for their short labours. Such visions and majestic descriptions shew that St. John was inspired by the same spirit of God, as the ancient patriarchs and prophets. --- I will show thee the things which must come to pass hereafter; i.e. after the things already revealed concerning the seven Churches, and therefore after the destruction of Jerusalem, which was about twenty years before St. John wrote this Apocalypse. (Witham)
