What does the Bible say about God's covenant with Israel?

In Ezekiel 20, God reminds the elders of Israel about the covenant made with their forefathers, where He pledged to be their God provided they obeyed His statutes. However, throughout history, they consistently broke this covenant due to their rebellions and idolatry. This narrative illustrates the failure of the covenant of works and highlights God's sovereignty, as He fulfills His promises for His name's sake. It also points to the need for a new and everlasting covenant, through which sinners can approach God based solely on Christ's righteousness. Thus, the covenant serves to show the depth of human sinfulness and the height of God's grace in redeeming a people for Himself.
