2 Chronicles 7:1 Now when Solomon had made an end of praying, the fire came down from heaven, and consumed the burnt offering and the sacrifices; and the glory of the LORD filled the house.
2 Chronicles 7:2 And the priests could not enter into the house of the LORD, because the glory of the LORD had filled the LORD’s house.
2 Chronicles 7:3 And when all the children of Israel saw how the fire came down, and the glory of the LORD upon the house, they bowed themselves with their faces to the ground upon the pavement, and worshipped, and praised the LORD, saying, For he is good; for his mercy endureth for ever.
2 Chronicles 7:4 Then the king and all the people offered sacrifices before the LORD.
2 Chronicles 7:5 And king Solomon offered a sacrifice of twenty and two thousand oxen, and an hundred and twenty thousand sheep: so the king and all the people dedicated the house of God.
The verse centers on "mercy", "children", "israel", "fire", "came", "down", "glory", and "lord". It is saying that the verse draws attention to "mercy" and "children", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 2's "And the priests could not enter into..." into verse 4's "Then the king and all the people...", so "mercy" and "children" 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 "mercy" and "children" with trust shaped by these words, not by a vague optimism outside the passage.
