The word 'today' in this divine declaration seems simple, but it carries immense weight, pointing to a specific, significant moment.
Beyond Ordinary Birthdays
When God says, "today I have begotten you," what 'today' does He mean? It's not referring to an ordinary birthday or even the moment of earthly conception. The ancient commentators point out that 'today' signifies a specific moment of manifestation and inauguration.
Inauguration and Declaration
For David, as a king anointed by God, 'today' marked the public manifestation of his God-given authority and his unique relationship to God as His son by adoption and calling. For Jesus Christ, the ultimate Son, 'today' finds its fullest meaning in His resurrection. It's the day His divine Sonship was powerfully declared and confirmed to the world, marking His inauguration as the reigning King over all.
