Isaías 60:21

All the Israelites will be righteous, whereas formerly they had been unrighteous, in their standing and in their state. And they will possess the Promised Land forever, rather than having to leave it because of their sins (cf. Genesis 17:8). Young wrote, "Inheritance of the land is a symbol of the future spiritual blessings that come to man through Christ." [Note: Young, 3:456.] If this is so, why did God give specific geographical boundaries for the Promised Land several times after Israel possessed the land partially? Israel would be the plant that God had nourished, and would now be healthy and thriving (cf. Isaiah 4:1; Isaiah 5:1-7; Isaiah 6:13; Isaiah 11:1; Isaiah 27:2-6; Isaiah 53:2; John 15:1-5). Her condition would glorify Him.
