God's purpose in choosing Israel was multifaceted, rooted in a divine plan to bring about salvation and to demonstrate humanity's need for Him. Initially, God selected Abraham for his unique qualities, seeing in him the potential to found a nation that would culminate in the birth of Jesus Christ, the central figure of His redemptive plan. Through Abraham's descendants, God intended Israel to be a conduit for blessing all mankind, as Christ had to come from a specific lineage to fulfill His role as Messiah. Israel was to serve as a special treasure to God, a people set apart from all others, maintaining a unique relationship with Him. They were called to be a kingdom of priests and a holy nation, acting as a mediatory nation between God and the rest of humanity, bridging the gap through their covenant with Him. This role involved obedience to His laws, showcasing His way of life as an example for other nations to emulate, with the potential to spread peace and prosperity if they adhered to His commandments. Additionally, God used Israel to advance His plan throughout history, positioning them to influence world events and prepare the environment for Christ's birth and ministry. Despite providing them with every physical and spiritual advantage—strong lineage, fertile land, and divine promises—Israel repeatedly failed to obey Him. This failure was part of God's purpose to illustrate that humanity, even under ideal circumstances, cannot succeed without His spiritual help, highlighting the necessity of His Holy Spirit and the New Covenant. Israel's history of shortcomings serves as a negative example for learning, admonishing others not to repeat their mistakes such as lust, idolatry, and disobedience. Their struggles and captivities over thousands of years stand as a classroom lesson for all peoples, demonstrating the impossibility of solving human problems without God's intervention. Yet, God has not abandoned Israel; He promises a future restoration where they will be gathered, given His Spirit, and finally fulfill their role as a model nation during the Millennium, influencing other nations to follow His ways. Ultimately, Israel's purpose includes a future opportunity for redemption, where they will revisit their past failures under God's guidance, understanding their errors and glorifying Him as intended from the beginning. Their temporary rejection has opened the way for others to be grafted into His plan, benefiting the whole world through the mysterious ways He works to bring about salvation for all.
