Passage
And the child grew, and waxed strong in spirit, and was in the deserts till the day of his showing unto Israel.
And the child grew, and waxed strong in spirit, and was in the deserts till the day of his showing unto Israel.
Luke 1:78 Because of the tender mercy of our God, Whereby the dayspring from on high shall visit us,
Luke 1:79 To shine upon them that sit in darkness and the shadow of death; To guide our feet into the way of peace.
Luke 1:80 And the child grew, and waxed strong in spirit, and was in the deserts till the day of his showing unto Israel.
The verse centers on "Spirit", "child", "grew", "waxed", "strong", "deserts", "till", and "showing". It is saying that the verse draws attention to "Spirit" and "child", so its meaning should be read from those terms before moving to application.
The prior verse says "To shine upon them that sit in...", giving immediate footing for "Spirit" and "child". In Luke context, the local focus is Christ, faith, and discipleship.
A plain takeaway is to answer the verse's own emphasis on "Spirit" and "child" with trust shaped by these words, not by a vague optimism outside the passage.
