What about this Contract?
Gen 17:
[8] And I[God] will give unto thee[Abraham], 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 to thy seed
2Ti 2:8 Remember that Jesus Christ of the seed of David was raised from the dead according to my gospel
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.
We need great caution in telling God what HE meant :>)
