Maybe Israel’s work was done the second Christ gave up His ghost on the cross of our salvation, and Israel is behind the curve because it fails to recognize Christ’s Divinity.
Read Romans 11 and you will see why they are “behind the curve”.
Maybe not.
While “Israelites” may have failed to recognize The God’s Messiach, it’s pretty obvious that The God has not failed to recognize “Israelites,” however they at this tine regard Him.
