God’s purpose and choice of Israel as His witness was for to be a light to the Gentiles. Through her, He would reveal to the Gentiles His character and His ways.
Psalm 98:2-3
The Lord has made known His salvation; His righteousness He has revealed in the sight of the nations. He has remembered His mercy and His faithfulness to the house of Israel; all the ends of the earth have seen the salvation of our God.
To fulfill that purpose, Israel had to:
Preserve His word (Romans 9:4; 15:4)
Prove God’s choice (Romans 9:11)
Give birth to Messiah Yeshua (Genesis 3:15; Galatians 4:4-5)
Invite Him to return (Matthew 23:37-39)
Be the reason for judging the nations (Joel 3:1-3; Zechariah 1:18-21; 12:1-4; Matthew 25:31-46).
PRAY ISRAEL WILL BE OBEDIENT AND FULFILL ALL OF GOD’S PURPOSES.
