Passage
And they entered into a covenant to seek the LORD God of their fathers with all their heart and with all their soul;
And they entered into a covenant to seek the LORD God of their fathers with all their heart and with all their soul;
2 Chronicles 15:10 So they gathered themselves together at Jerusalem in the third month, in the fifteenth year of the reign of Asa.
2 Chronicles 15:11 And they offered unto the LORD the same time, of the spoil which they had brought, seven hundred oxen and seven thousand sheep.
2 Chronicles 15:12 And they entered into a covenant to seek the LORD God of their fathers with all their heart and with all their soul;
2 Chronicles 15:13 That whosoever would not seek the LORD God of Israel should be put to death, whether small or great, whether man or woman.
2 Chronicles 15:14 And they sware unto the LORD with a loud voice, and with shouting, and with trumpets, and with cornets.
The verse centers on "entered", "covenant", "seek", "lord", "fathers", "heart", and "soul". It is saying that the verse draws attention to "entered" and "covenant", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 11's "And they offered unto the LORD the..." into verse 13's "That whosoever would not seek the LORD...", so "entered" and "covenant" belong inside that flow. In 2 Chronicles context, the local focus is covenant, worship, and faithfulness.
A plain takeaway is to answer the verse's own emphasis on "entered" and "covenant" with trust shaped by these words, not by a vague optimism outside the passage.
