Excellent post, the Bible says that we are joint heirs with Christ, which means that the order of the inheritance exists from the foundation of the world, where did the Christ come from? of David's lineage. Hence a passage in the word refers to JESUS as the son of David.

As we inherit the divine, we also inherit the sinful nature, thanks to the act of love of God the Father to offer his son to die for us the plan of redemption of humanity was carried out, henceforth all we accept that JESUS is the savior of the world, we have access to the throne of grace, to the divine inheritance.

We, in this corruptible body we are heirs of pacados, but by Jesus we can change our history, he through his sacrifice on the cross justified us forever and thanks to him we can be called children of God.
