Passage
Thou wilt perform the truth to Jacob, and the mercy to Abraham, which thou hast sworn unto our fathers from the days of old.
Thou wilt perform the truth to Jacob, and the mercy to Abraham, which thou hast sworn unto our fathers from the days of old.
Micah 7:18 Who is a God like unto thee, that pardoneth iniquity, and passeth by the transgression of the remnant of his heritage? he retaineth not his anger for ever, because he delighteth in mercy.
Micah 7:19 He will turn again, he will have compassion upon us; he will subdue our iniquities; and thou wilt cast all their sins into the depths of the sea.
Micah 7:20 Thou wilt perform the truth to Jacob, and the mercy to Abraham, which thou hast sworn unto our fathers from the days of old.
The verse centers on "mercy", "thou", "wilt", "perform", "truth", "jacob", and "abraham". It is saying that the verse draws attention to "mercy" and "thou", so its meaning should be read from those terms before moving to application.
The prior verse says "He will turn again he will have...", giving immediate footing for "mercy" and "thou". In Micah context, the local focus is covenant, worship, and faithfulness.
A plain takeaway is to answer the verse's own emphasis on "mercy" and "thou" with trust shaped by these words, not by a vague optimism outside the passage.
