Commenting on Psa 90:2, Mark Jones (Reformed) argues it should be read Christocentrically:
Psalm 90 sets forth a rather
magnificent testimony of the person of Christ. Verse 2 refers to Jesus: ‘Before
the mountains were brought forth, or ever you had formed the earth and the
world, from everlasting to everlasting you are God.’ Here the glory of his
person comes into full view. Jesus is also referred to in the rest of the
psalm: he was taught to number his days (90:12); he passed away under the wrath
of God (90:9); but God also established the work of Christ’s hands (90:17).
Reading Psalm 90 Christocentrically, as all psalms need to be read, brings it
to life. The verses that speak about God refer to Jesus; but the verses that
speak about man also refer to Jesus. Now exalted in the heavenly places, his
days have no number. Those who belong to him will not be able to number
their days when they receive eternal life. (Mark Jones, Knowing Christ [Edinburgh:
The Banner of Truth Trust, 2015], 37-38, emphasis added)
Reading Psalm 90 from the
perspective of Jesus highlights the amazing condescension. Many see Christ
present in verse 2 . . . While this is true, there are verses here that Jesus
would have connected to his earthly life and ministry. In verse 23, for
example, we are taught to ‘number of days’ in order to ‘get a heart of wisdom.’
Jesus did that. He numbered his days as he contemplated the fleeting character
of this earthly life, and he made every day count. More than that God’s wrath
brought Jesus’ life to an end, one he experienced with a troubled heart (90:7;
see also Matt. 27:46). He ended his years like a sigh (90:9; see also Luke
23:46). But he also knew that the works of his hands would be established
because the favour of the Lord was upon him (90:17). (Ibid., 86-87)
