GEN 12:
To a land that I will show you.
2
I will make you a great nation;
Gen 15:
18 On the same day the Lord made a covenant with Abram, saying:
“To your descendants
I have given this land, from the river of Egypt to the great river, the River Euphrates— 19 the Kenites, the Kenezzites, the Kadmonites, 20 the Hittites, the Perizzites, the Rephaim, 21 the Amorites, the Canaanites, the Girgashites, and the Jebusites.”
GEN 17
8 Also I give to you and your descendants after you
the land in[f] which you are a stranger, all the land of Canaan, as an everlasting possession; and I will be their God.”
GEN 26:
2 Then the Lord appeared to him and said: “Do not go down to Egypt; live in the land of which I shall tell you. 3 Dwell in this land, and I will be with you and bless you; for
to you and your descendants I give all these lands, and I will perform the oath which I swore to Abraham your father. 4 And I will make your descendants multiply as the stars of heaven;
I will give to your descendants all these lands
GEN 28
13 And behold, the Lord stood above it and said: “I
am the Lord God of Abraham your father and the God of Isaac;
the land on which you lie I will give to you and your descendants.
GEN 35:
9 Then God appeared to Jacob again, when he came from Padan Aram, and blessed him. 10 And God said to him, “Your name
is Jacob; your name shall not be called Jacob anymore, but Israel shall be your name.” So He called his name Israel. 11 Also God said to him: “I
am God Almighty. Be fruitful and multiply; a nation and a company of nations shall proceed from you, and kings shall come from your body. 12 The
land which I gave Abraham and Isaac I give to you; and to your descendants after you I give this land.”
tell me, were these particular promises made to spiritual children, or physical children?
If spiritual. Why did God write lev 26? And why are we not being blessed by these promises today? (lev 26 tells us why physical children are not being blessed by them today, because of their sins)
Gen 15:18 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:
Singular seed - Christ.
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.
Singular seed - Christ.
Gen 26:3 Sojourn in this land, and I will be with thee, and will bless thee; for unto thee, and unto
thy seed, I will give all these countries, and I will perform the oath which I sware unto Abraham thy father;
Singular seed - Christ.
Gen 28:13 And, behold, the LORD stood above it, and said, I am the LORD God of Abraham thy father, and the God of Isaac: the land whereon thou liest, to thee will I give it, and to
thy seed;
Singular seed - Christ.
Gen 35:12 And the land which I gave Abraham and Isaac, to thee I will give it, and to
thy seed after thee will I give the land.
Singular seed - Christ.
Here is what Paul said about that SINGULAR seed.
Gal_3:16 Now to Abraham and his seed were the promises made.
He saith not, And to seeds, as of many; but as of one, And to thy seed, which is Christ.
Every one of the verses you quoted refer to a singular seed Christ and Paul made it clear in Galatians that "thy seed" means ONE SEED.
You have a valid point on Leviticus 26, but you may have missed a couple of things.
Lev 26:3 If ye walk in my statutes, and keep my commandments, and do them;
1) They had to obey the commandment FLAWLESSLY in order to live in that land.
2) That was the Old Covenant, Israel is not under that covenant any more.
