Revelation 19:9

‘And he says to me, “Write, blessed are those who are bid to the marriage supper of the Lamb”.'

Those who are bid to the marriage supper of the Lamb are truly blessed for they are invited as the Bride. The ‘he' must be the angel of Revelation 1:1, who brought to John his visions. Those visions are now almost complete.

Jesus Himself likened His call to men to repent and enter under the Kingly Rule of God to an invitation to a wedding feast (Matthew 22:2; compare Matthew 25:1) where the emphasis was on individual response. Those words are in mind here. But He also presented Himself as the Bridegroom coming for His bride (Mark 2:19; John 3:29). For the church as the bride see also 2 Corinthians 11:2; Ephesians 5:27. For the true Israel as God's bride see Hosea 2:19; Isaiah 54:1; and Ezekiel 16:8 where God Himself prepares the bride Thus bride and guests are one.

‘And he says to me, “These are the true words of God”.'

The angel emphasises the truth of all that John has seen. The seven visions have been given and now they receive heavenly ratification. This is introduced now so that no attention is taken from the final Coming of the Word of God (Revelation 19:11 on).
