Are we to approach the throne of grace in prayer today as indicated in Hebrews 4:16?
The word throne does not appear in any of the epistles Paul wrote after Acts 28:28. It is not found in the gospel of John which was also written this side of Acts. Throne has to do with a King and a kingdom. There is no place for a throne in The Church. In the plural, it occurs in Col 1:16, but it is concerning thrones, dominions, and the like in heaven and earth, not the throne of God.
