God's perfect creation was ruined by sin way back in the beginning, but because of God's great love for His people, He made a way to rescue them. He promised Adam and Eve that a rescuer would come through their line and we have been tracing that promise from Adam and Eve to Noah, through Abraham, to Judah, through generations that eventually led to David and Solomon.

David and Solomon were known as the greatest earthly kings for God's people. The kingdom was powerful and large, and they had a time of peace and wealth, but it didn't last long. The consequence for Solomon's sin was that the kingdom would be divided. 

The nation was divided into two kingdoms: Israel in the north and Judah in the south. David's family continued ruling in Judah while other tribes ruled in Israel.

Some kings listened to God for a while, but they didn't stay faithful to God. Many of the kings rejected God and worshipped false gods Instead. Some kings even led the people Into terrible sin. Could mankind become so sinful that God would end His promise? No! God loves His people despite their sin.

During the time of kings, God send prophets (messengers) to guide the kings and the people. The prophets reminded the people to turn away from sin and warned that continued disobedience would bring consequences. They also reminded the people that God would send a future king and rescuer. 

Even though the kings and people sinned, God didn't forget his promise to send a savior through the line of David. We see His faithfulness in this verse:

The steadfast love of the LORD never ceases; his mercies never come to an end; they are new every morning; great is your faithfulness.

Lamentations 3:22-23
