2 Chronicles 7:1-3 NKJV
When Solomon had finished praying, fire came down from heaven and consumed the burnt offering and the sacrifices; and the glory of the LORD filled the temple. And the priests could not enter the house of the LORD, because the glory of the LORD had filled the LORD's house. When all the children of Israel saw how the fire came down, and the glory of the LORD on the temple, they bowed their faces to the ground on the pavement, and worshiped and praised the LORD, saying: "For He is good, For His mercy endures forever."
Solomon had just finished dedicating the temple to the Lord. As they offered sacrifices, the glory of the Lord showed up and a powerful sign from Heaven appeared. Fire came down and consumed the offering and sacrifice. The glory of God was so thick that the priests could not pass through it to go into the temple. In the midst of this great display of God’s power, what did the Jews focus on when they worshipped? It was God’s goodness and mercy. Whenever there was a significant moment in the history of Israel, it was very common for them to praise the Lord for His goodness. Even when they were in warfare, we see mention of God’s goodness. Although they mentioned His power and greatness sometimes, the thing that got more emphasis when they worshipped was God’s goodness. God’s goodness is what makes Him so great.
