@Reba1 -- look up the Abrahamic Covenant -- it's unconditional -- there's an article "What is the Abrahamic Covenant" with Got Questians -- a very good explanation. There are 5 areas to be considered. They Will have all the land promised.
Sue Ever tell your child IF you wash the dishes i will pay you $2.00 . Or something like You know your allowance depends on you doing your chores. If you want to drive the car keep your grads up ? Those are conditions.
I try to always list chapter and verse so the context can be read in full.
Gen 17:7 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.
Gen 17:8 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.
Gen 17:9 And God said unto Abraham,
Thou shalt keep my covenant therefore, thou, and thy seed after thee in their generations.
Gen 17:10 This is my covenant
, which ye shall keep, between me and you and thy seed after thee; Every man child among you shall be circumcised.
Gen 17:14 And the uncircumcised man child whose flesh of his foreskin is not circumcised, that soul shall be cut off from his people;
he hath broken my covenant.
Gen 18:18 Seeing that Abraham shall surely become a great and mighty nation, and all the nations of the earth shall be blessed in him?
Gen 18:19 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.
Gen 26:4 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;
Gen 26:5
Because that Abraham obeyed my voice, and kept my charge, my commandments, my statutes, and my laws
Lev 26:40
If they shall confess their iniquity, and the iniquity of their fathers, with their trespass which they trespassed against me, and that also they have walked contrary unto me;
Lev 26:41 And that I also have walked contrary unto them, and have brought them into the land of their enemies;
if then their uncircumcised hearts be humbled, and they then accept of the punishment of their iniquity:
Lev 26:42
Then will I remember my covenant with Jacob, and also my covenant with Isaac, and also my covenant with Abraham will I remember; and I will remember the land.
Deu 7:12 Wherefore it shall come to pass,
if ye hearken to these judgments, and keep, and do them, that the LORD thy
God shall keep unto thee the covenant and the mercy which he sware unto thy fathers:
Gen17:7 tells us this is an everlasting covenant. Bible history and world history shows us it was not everlasting . They do not have
that land today. God is faithful in His promises . It was not God that broke the covenant it was them.
Moving on to Joshua , the book is full of details How Josh trusted the Lord and how they were blessed
Jos 21:43 And the LORD gave unto Israel all the land which he sware to give unto their fathers;
and they possessed it, and dwelt therein.
Jos 21:44 And the LORD gave them rest round about, according to
all that he sware unto their fathers: and there stood not a man of all their enemies before them; the LORD delivered all their enemies into their hand.
Jos 21:45
There failed not ought of any good thing which the LORD had spoken unto the house of Israel; all came to pass.
Because of the Scriptures posted , and others , i understand the promise/covenant with Abram/Abraham to base on conditions . I also see/read there in Joshua god kept His part.
