But the mercy of the Lord is from everlasting to everlasting upon them that fear him, and his righteousness unto children’s children;
God is generation-minded. He is concerned about future generations.
 After these things the word of the Lord came unto Abram in a vision, saying, Fear not, Abram: I am thy shield, and thy exceeding great reward.  And Abram said, Lord God , what wilt thou give me, seeing I go childless, and the steward of my house is this Eliezer of Damascus? And Abram said, Behold, to me thou hast given no seed: and, lo, one born in my house is mine heir.  And, behold, the word of the Lord came unto him, saying, This shall not be thine heir; but he that shall come forth out of thine own bowels shall be thine heir.  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.
 And when Abram was ninety years old and nine, the Lord appeared to Abram, and said unto him, I am the Almighty God; walk before me, and be thou perfect.  And I will make my covenant between me and thee, and will multiply thee exceedingly.  And Abram fell on his face: and God talked with him, saying,  As for me, behold, my covenant is with thee, and thou shalt be a father of many nations.  Neither shall thy name any more be called Abram, but thy name shall be Abraham; for a father of many nations have I made thee.  And I will make thee exceeding fruitful, and I will make nations of thee, and kings shall come out of thee.  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.  And God said unto Abraham, Thou shalt keep my covenant therefore, thou, and thy seed after thee in their generations.
There are 33 different occasions in the Word where God is known as “the God of Abraham, Isaac and Jacob.”
God has chosen family to be the avenue through which he brings forth generational blessing and righteousness.
 Behold, I will send you Elijah the prophet before the coming of the great and dreadful day of the Lord :  And he shall turn the heart of the fathers to the children, and the heart of the children to their fathers, lest I come and smite the earth with a curse.
Of the 10 commandments, only 1 has an attached promise: children honor your father and mother that it may be well with you…
God is serious about succession. Family is meant to be the strength of our society. Parents should train up their children in the ways of the Lord (Proverbs 22:6). To “train” means to narrow. Narrow their path to God’s ways.
We can’t be so concerned with ourselves and our own happiness that we sacrifice the raising of our children. We have to raise them in God’s ways, with future generations in mind.
 And God said unto Abraham, As for Sarai thy wife, thou shalt not call her name Sarai, but Sarah shall her name be .  And I will bless her, and give thee a son also of her: yea, I will bless her, and she shall be a mother of nations; kings of people shall be of her.
 And the Lord said, Shall I hide from Abraham that thing which I do;  Seeing that Abraham shall surely become a great and mighty nation, and all the nations of the earth shall be blessed in him?  For I know him, that he will command his children and his household after him, and they shall keep the way of the Lord , to do justice and judgment; that the Lord may bring upon Abraham that which he hath spoken of him.
God chose Abraham to be the father of many nations because He knew He could trust Abraham to raise his children to honor the Lord. God trusted that Abraham would be the primary influencer of his family, and that he would make sure the future generations were secure in the faith.
2 Kings 18:3-7
 And he did that which was right in the sight of the Lord , according to all that David his father did.  He removed the high places, and brake the images, and cut down the groves, and brake in pieces the brasen serpent that Moses had made: for unto those days the children of Israel did burn incense to it: and he called it Nehushtan.  He trusted in the Lord God of Israel; so that after him was none like him among all the kings of Judah, nor any that were before him.  For he clave to the Lord , and departed not from following him, but kept his commandments, which the Lord commanded Moses.  And the Lord was with him; and he prospered whithersoever he went forth: and he rebelled against the king of Assyria, and served him not.
Hezekiah honored the Lord during his reign. However, he wasn’t concerned with the future of his household. When he became sick, God had mercy on him and gave him 15 extra years of life so that he could get his house in order. During that time, he had a son, Manasseh.
2 Kings 20:1-3,6, 14-21
 In those days was Hezekiah sick unto death. And the prophet Isaiah the son of Amoz came to him, and said unto him, Thus saith the Lord , Set thine house in order; for thou shalt die, and not live.  Then he turned his face to the wall, and prayed unto the Lord , saying,  I beseech thee, O Lord , remember now how I have walked before thee in truth and with a perfect heart, and have done that which is good in thy sight. And Hezekiah wept sore.  And I will add unto thy days fifteen years; and I will deliver thee and this city out of the hand of the king of Assyria; and I will defend this city for mine own sake, and for my servant David’s sake.
 Then came Isaiah the prophet unto king Hezekiah, and said unto him, What said these men? and from whence came they unto thee? And Hezekiah said, They are come from a far country, even from Babylon.  And he said, What have they seen in thine house? And Hezekiah answered, All the things that are in mine house have they seen: there is nothing among my treasures that I have not shewed them.  And Isaiah said unto Hezekiah, Hear the word of the Lord .  Behold, the days come, that all that is in thine house, and that which thy fathers have laid up in store unto this day, shall be carried into Babylon: nothing shall be left, saith the Lord .  And of thy sons that shall issue from thee, which thou shalt beget, shall they take away; and they shall be eunuchs in the palace of the king of Babylon.  Then said Hezekiah unto Isaiah, Good is the word of the Lord which thou hast spoken. And he said, Is it not good , if peace and truth be in my days?  And the rest of the acts of Hezekiah, and all his might, and how he made a pool, and a conduit, and brought water into the city, are they not written in the book of the chronicles of the kings of Judah? And Hezekiah slept with his fathers: and Manasseh his son reigned in his stead.
When King Hezekiah died, his 12 year old son Manasseh became king. This means Manasseh was born during the grace period that God gave Hezekiah. But King Hezekiah was only concerned with “his days”, and not concerned with the future generations. Because of this, as soon as he died, his son undid all the good things he had done.
2 Kings 21:1-3
 Manasseh was twelve years old when he began to reign, and reigned fifty and five years in Jerusalem. And his mother’s name was Hephzi-bah.  And he did that which was evil in the sight of the Lord , after the abominations of the heathen, whom the Lord cast out before the children of Israel.  For he built up again the high places which Hezekiah his father had destroyed; and he reared up altars for Baal, and made a grove, as did Ahab king of Israel; and worshipped all the host of heaven, and served them.
Don’t be so consumed with your life that you don’t secure the next generation.
 And thou shalt love the Lord thy God with all thine heart, and with all thy soul, and with all thy might.  And these words, which I command thee this day, shall be in thine heart:  And thou shalt teach them diligently unto thy children, and shalt talk of them when thou sittest in thine house, and when thou walkest by the way, and when thou liest down, and when thou risest up.
