Does God truly 'forsake' us? How can His anger be so brief, yet feel so long?
The verse speaks of God forsaking His people "for a small moment." Commentators note that this "moment" is intensely relative. Though it might feel like an eternity to those experiencing it, like the seventy years of Babylonian exile, in the grand sweep of God's eternal plan and His everlasting kindness, it is but a brief instant.
This isn't to diminish the pain of that "moment." God's anger, though temporary, is real, arising from His deep love and His grief over sin. It's often understood as His 'hiding His face' (as mentioned in verse 8) rather than a complete abandonment. It's a discipline, a temporary withdrawal of His manifest presence to correct and refine His people, not a final rejection.
