CLAIM: David prophesies of the rage of the nations against Jesus that will fully manifest during the Great Tribulation in the Armageddon campaign. The rage of the nations in this psalm was partially fulfilled when they persecuted the saints in the early Church (Acts 4:28-31).
Unclear, but probably not.
As with most of the Psalms, many try to make End Times connections, but many of them, even if correct, will be hard to determine. This one seems doubtful, however, from the get go, because Psalm 2:12 which says “Blessed are all who take refuge in Him”. Since this would apply to all peoples since Jesus’ coming, so it is doubtful that this is referring to any specific time other than the current age, although that application will extend until the final judgment. Even then, it is doubtful that we will stop “kissing the Son”, however, the rulers at that point, only the saved, would not need to be so warned. But, we may still sing it.
Why the need to connect this to Armageddon is presented is beyond the text of the verse.
