As far as the east is from the west, so far hath he removed our transgressions from us.
As far as the east is from the west, so far hath he removed our transgressions from us.
Psalms 103:10 He hath not dealt with us after our sins; nor rewarded us according to our iniquities.
Psalms 103:11 For as the heaven is high above the earth, so great is his mercy toward them that fear him.
Psalms 103:12 As far as the east is from the west, so far hath he removed our transgressions from us.
Psalms 103:13 Like as a father pitieth his children, so the LORD pitieth them that fear him.
Psalms 103:14 For he knoweth our frame; he remembereth that we are dust.
The verse centers on "transgressions", "east", "west", "hath", and "removed". It is saying that the verse draws attention to "transgressions" and "east", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 11's "For as the heaven is high above..." into verse 13's "Like as a father pitieth his children...", so "transgressions" and "east" 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 "transgressions" and "east" with trust shaped by these words, not by a vague optimism outside the passage.
