Passage
Also darkness hideth not from Thee, And night as day shineth, as <FI>is<Fi> darkness so <FI>is<Fi> light.
Also darkness hideth not from Thee, And night as day shineth, as <FI>is<Fi> darkness so <FI>is<Fi> light.
Psalms 139:10 Also there Thy hand doth lead me, And Thy right hand doth hold me.
Psalms 139:11 And I say, `Surely darkness bruiseth me, Then night <FI>is<Fi> light to me.
Psalms 139:12 Also darkness hideth not from Thee, And night as day shineth, as <FI>is<Fi> darkness so <FI>is<Fi> light.
Psalms 139:13 For Thou--Thou hast possessed my reins, Thou dost cover me in my mother's belly.
Psalms 139:14 I confess Thee, because that <FI>with<Fi> wonders I have been distinguished. Wonderful <FI>are<Fi> Thy works, And my soul is knowing <FI>it<Fi> well.
The verse centers on "light", "darkness", "hideth", "thee", "night", and "shineth". It is saying that the contrast between light and darkness marks a real divide in how people respond to God's work.
The nearby context moves from verse 11's "And I say Surely darkness bruiseth me..." into verse 13's "For Thou--Thou hast possessed my reins Thou...", so "light" and "darkness" belong inside that flow. In Psalms context, the local focus is worship, trust, the LORD's kingship, and covenant mercy.
A plain takeaway is to answer the verse's own emphasis on "light" and "darkness" with trust shaped by these words, not by a vague optimism outside the passage.
