Ready to rule

The Laodiceans are invited to buy gold, garments, and ointment, preparations for a wedding. They are also invited to buy the equipment to rule.

White raiment is worn by the elders who sit enthroned in heaven at the beginning of Revelation. They are also wearing gold crowns (Revelation 4:4). The Laodiceans are being invited to share in that heavenly rule, where they will wear white and gold crowns and see clearly with anointed eyes. Since eyes are organs of judgment, the eye slave that allows them to see is an invitation to have a share in heavenly judgments.

In short, they shop for what they need to sit with Jesus on his throne (Revelation 3:21).
