Now the LORD had said unto Abram, Get thee out of thy country, and from thy kindred, and from thy father's house, unto a land that I will shew thee: And I will make of thee a great nation, and I will bless thee, and make thy name great; and thou shalt be a blessing: And I will bless them that bless thee, and curse him that curseth thee: and in thee shall all families of the earth be blessed. (Genesis 12:1-3)
Why is Israel so important?
Israel is important to Christians because she is important to God. When God called Abraham (then called Abram) out of Ur of the Chaldees, God knew of the future actions of his descendants, the Israelites. After God called Abraham from the land of his birth and the land he was most familiar with, God used this calling on Abraham's life and the promises, of land inheritance and as the line which the Messiah would come, as a way to shape his faith in God. As time went by, Abraham became known as God's friend and a man of great faith. Some of God's promise to Abraham were only fulfilled after Abraham's passing; but God's promises to Abraham have clearly been fulfilled, and are still being fulfilled even to this day.
God's promises to Abraham
1. Land inheritance
And the LORD said unto Abram, after that Lot was separated from him, Lift up now thine eyes, and look from the place where thou art northward, and southward, and eastward, and westward: For all the land which thou seest, to thee will I give it, and to thy seed for ever. (Genesis 13:14-15)
In the same day the LORD made a covenant with Abram, saying, Unto thy seed have I given this land, from the river of Egypt unto the great river, the river Euphrates: The Kenites, and the Kenizzites, and the Kadmonites, And the Hittites, and the Perizzites, and the Rephaims, And the Amorites, and the Canaanites, and the Girgashites, and the Jebusites. (Genesis 15:18-21)
And I will establish my covenant between me and thee and thy seed after thee in their generations for an everlasting covenant, to be a God unto thee, and to thy seed after thee. And I will give unto thee, and to thy seed after thee, the land wherein thou art a stranger, all the land of Canaan, for an everlasting possession; and I will be their God. (Genesis 17:8-7)
2. Innumerable descendants
And I will make thy seed as the dust of the earth: so that if a man can number the dust of the earth, then shall thy seed also be numbered. (Genesis 13:16)
And he brought him forth abroad, and said, Look now toward heaven, and tell the stars, if thou be able to number them: and he said unto him, So shall thy seed be. And he believed in the LORD; and he counted it to him for righteousness.
(Genesis 15:5-6)
3. Nations to be blessed through descendants
And in thy seed shall all the nations of the earth be blessed; because thou hast obeyed my voice. (Genesis 22:18)
And I will make thy seed to multiply as the stars of heaven, and will give unto thy seed all these countries; and in thy seed shall all the nations of the earth be blessed (Genesis 26:4)
Abraham's descendants, the Israelites
The Bible says that no matter what the Israelites do, God will never forsake them. God will judge them if they are disobedient and practice evil, but He will never leave them desolate forever:
Thus saith the LORD, which giveth the sun for a light by day, and the ordinances of the moon and of the stars for a light by night, which divideth the sea when the waves thereof roar; The LORD of hosts is his name: If those ordinances depart from before me, saith the LORD, then the seed of Israel also shall cease from being a nation before me for ever. Thus saith the LORD; If heaven above can be measured, and the foundations of the earth searched out beneath, I will also cast off all the seed of Israel for all that they have done, saith the LORD. (Jeremiah 31:35-37)
God did not permanently remove the nation of Israel because they had rejected their Messiah:
I say then, Hath God cast away his people? God forbid. For I also am an Israelite, of the seed of Abraham, of the tribe of Benjamin. Wot ye not what the scripture saith of Elias? how he maketh intercession to God against Israel, saying, Lord, they have killed thy prophets, and digged down thine altars; and I am left alone, and they seek my life. But what saith the answer of God unto him? I have reserved to myself seven thousand men, who have not bowed the knee to the image of Baal. Even so then at this present time also there is a remnant according to the election of grace. What then? Israel hath not obtained that which he seeketh for; but the election hath obtained it, and the rest were blinded (According as it is written, God hath given them the spirit of slumber, eyes that they should not see, and ears that they should not hear;) unto this day. And David saith, Let their table be made a snare, and a trap, and a stumblingblock, and a recompence unto them: Let their eyes be darkened, that they may not see, and bow down their back alway. (Romans 11:1-10)
In light of their rejecting the Messiah, God blinded them: but only to open the door of salvation to the Gentiles, and provoke the Jews to jealousy to ultimately save them:
I say then, Have they stumbled that they should fall? God forbid: but rather through their fall salvation is come unto the Gentiles, for to provoke them to jealousy. Now if the fall of them be the riches of the world, and the diminishing of them the riches of the Gentiles; how much more their fulness? For I speak to you Gentiles, inasmuch as I am the apostle of the Gentiles, I magnify mine office: If by any means I may provoke to emulation them which are my flesh, and might save some of them. For if the casting away of them be the reconciling of the world, what shall the receiving of them be, but life from the dead? (Romans 11:11-15)
Some believe, from their interpretation of the wicked husbandmen parable which Jesus spoke, that God is done with Israel:
When the lord therefore of the vineyard cometh, what will he do unto those husbandmen? They say unto him, He will miserably destroy those wicked men, and will let out his vineyard unto other husbandmen, which shall render him the fruits in their seasons. Jesus saith unto them, Did ye never read in the scriptures, The stone which the builders rejected, the same is become the head of the corner: this is the Lord's doing, and it is marvellous in our eyes? Therefore say I unto you, The kingdom of God shall be taken from you, and given to a nation bringing forth the fruits thereof. And whosoever shall fall on this stone shall be broken: but on whomsoever it shall fall, it will grind him to powder. And when the chief priests and Pharisees had heard his parables, they perceived that he spake of them. (Matthew 21:40-45)To interpret the above passage as God being done with Israel is simply unfounded. One reason is because the husbandmen were the rulers, not the people; another reason is because God had clearly stated in Jeremiah 31:35-37 and Romans 11:1-15 that God will never forsake Israel. The final reason is because the parable does not state how long the vineyard will be taken from them and given to another nation.
Israel to be redeemed
For I would not, brethren, that ye should be ignorant of this mystery, lest ye should be wise in your own conceits; that blindness in part is happened to Israel, until the fulness of the Gentiles be come in. And so all Israel shall be saved: as it is written, There shall come out of Sion the Deliverer, and shall turn away ungodliness from Jacob: For this is my covenant unto them, when I shall take away their sins. (Romans 11:25-27)
