Hebrews 9:
6 Now when these things were thus ordained, the priests went always into the first tabernacle, accomplishing the service of God.
7 But into the second went the high priest alone once every year, not without blood, which he offered for himself, and for the errors of the people:
8 The Holy Ghost this signifying, that the way into the holiest of all was not yet made manifest, while as the first tabernacle was yet standing:
9 Which was a figure for the time then present, in which were offered both gifts and sacrifices, that could not make him that did the service perfect, as pertaining to the conscience;
10 Which stood only in meats and drinks, and divers washings, and carnal ordinances, imposed on them until the time of reformation.
11 But Christ being come an high priest of good things to come, by a greater and more perfect tabernacle, not made with hands, that is to say, not of this building;
12 Neither by the blood of goats and calves, but by his own blood he entered in once into the holy place, having obtained eternal redemption for us.
13 For if the blood of bulls and of goats, and the ashes of an heifer sprinkling the unclean, sanctifieth to the purifying of the flesh:
14 How much more shall the blood of Christ, who through the eternal Spirit offered himself without spot to God, purge your conscience from dead works to serve the living God?
15 And for this cause he is the mediator of the new testament, that by means of death, for the redemption of the transgressions that were under the first testament, they which are called might receive the promise of eternal inheritance.
It is by the blood of Christ that we who also partake in His death and resurrection through repentance and Spiritual renewal of our inner man and have been made renewed again by the Holy Spirit that we also have the same inheritance of Abraham that we will have life eternal with the Father and will not be damned to the lake of fire. We are set free from the generational curse of the law through Gods new covenant as the old covenant carried with it a curse if you did not follow all the law to the letter, but now set free from the curse by grace.
As far as sickness and disease or even barrenness things we bring upon ourselves by the way we take care of our bodies. I know God heals, but I also believe this flesh will not live forever and when times of afflictions come upon us is the times that the trying of our faith worketh patience.
