Passage
Thou hast set our iniquities before thee, our secret [sins] in the light of thy countenance.
Thou hast set our iniquities before thee, our secret [sins] in the light of thy countenance.
Psalms 90:6 In the morning it flourisheth and groweth up; in the evening it is cut down and withereth.
Psalms 90:7 For we are consumed by thine anger, and by thy fury are we troubled.
Psalms 90:8 Thou hast set our iniquities before thee, our secret [sins] in the light of thy countenance.
Psalms 90:9 For all our days pass away in thy wrath: we spend our years as a [passing] thought.
Psalms 90:10 The days of our years are threescore years and ten; and if, by reason of strength, they be fourscore years, yet their pride is labour and vanity, for it is soon cut off, and we fly away.
The verse centers on "light", "iniquities", "thou", "hast", "before", "thee", "secret", and "sins". It is saying that the verse draws attention to "light" and "iniquities", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 7's "For we are consumed by thine anger..." into verse 9's "For all our days pass away in...", so "light" and "iniquities" 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 "iniquities" with trust shaped by these words, not by a vague optimism outside the passage.
