God had made a covenant with Abraham, and He committed to keeping that covenant through the line of Isaac and Jacob. God had committed to making the nation of Israel a mighty nation with a land, a king, and an eternally blessed people. Those covenants were all unconditional—God had obligated Himself without any requirement on the part of the recipients of His covenant promises.
In Exodus chapter 19, God announces for Israel a conditional covenant. If they would keep His covenant, Israel would be a people for His own possession and a kingdom of priests and a holy nation.
These who believe are referred to as a kingdom, as those who believe in Jesus are transferred to His kingdom. Believers are also considered priests in that we are interceding on behalf of people that they might believe in the Lord. Those who are called a kingdom and priests have an obligation to walk in a manner worthy of His calling and ought to be actively proclaiming His excellencies so that others may come to know Him.
Title: A Nation of Priests
