And all the sons of Israel are looking on the descending of the fire, and the honour of Jehovah on the house, and they bow--faces to the earth--on the pavement, and do obeisance, and give thanks to Jehovah, for good, for to the age <FI> is<Fi> His kindness.
2 Chronicles 7:1 And at Solomon's finishing to pray, then the fire hath come down from the heavens, and consumeth the burnt-offering and the sacrifices, and the honour of Jehovah hath filled the house,
2 Chronicles 7:2 and the priests have not been able to go in unto the house of Jehovah, because the honour of Jehovah hath filled the house of Jehovah.
2 Chronicles 7:3 And all the sons of Israel are looking on the descending of the fire, and the honour of Jehovah on the house, and they bow--faces to the earth--on the pavement, and do obeisance, and give thanks to Jehovah, for good, for to the age <FI> is<Fi> His kindness.
2 Chronicles 7:4 And the king and all the people are sacrificing a sacrifice before Jehovah,
2 Chronicles 7:5 and king Solomon sacrificeth the sacrifice of the herd, twenty and two thousand, and of the flock, a hundred and twenty thousand, and the king and all the people dedicate the house of God.
The verse centers on "for good", "sons", "israel", "looking", "descending", "fire", "honour", and "jehovah". It is saying that the verse draws attention to "for good" and "sons", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 2's "and the priests have not been able..." into verse 4's "And the king and all the people...", so "for good" and "sons" 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 "for good" and "sons" with trust shaped by these words, not by a vague optimism outside the passage.
