That would only be as it relates to bondage to the sin nature (the "flesh" as noted in the Scripture below). The unregenerate (those who have not been born again) are within the kingdom of darkness because Satan is "the god of this world", and "the whole world lieth in wickedness".
EPHESIANS 2
1 And you hath he quickened, who were dead in trespasses and sins;
2 Wherein in time past ye walked according to the course of this world, according to the prince of the power of the air [Satan], the spirit that now worketh in the children of disobedience:
3 Among whom also we all had our conversation in times past in the lusts of our flesh, fulfilling the desires of the flesh and of the mind; and were by nature the children of wrath, even as others.
But God owes Satan absolutely nothing. It is false doctrine to claim (a) that Satan had any rights of any kind (b) that a ransom was paid to Satan or (c) that Christ suffered in Hell (the Lake of Fire) AFTER He died on the cross. These are the mistaken ideas of Word of Faith preachers.
Christ offered Himself to God as the perfect sacrifice for the sins of the whole world. The sin debt was paid to God the Father by the Son. The ransom was paid to God the Father since Christians are the purchased possession of God: For ye are bought with a price: therefore glorify God in your body, and in your spirit, which are God's. (1 Cor 6:20)
Take heed therefore unto yourselves, and to all the flock, over the which the Holy Ghost hath made you overseers, to feed the church of God, which he hath purchased with his own blood. (Acts 20:28)
That precious blood was Christ was sprinkled on the Mercy Seat in the Heavenly Sanctuary. And that is why Christ is the propitiation -- fully satisfactory sacrifice -- to God on behalf of sinners.
I love the marriage symbolism that Jesus Himself evoked at the Passover celebration, on the night before He died. The "bride price" was the precious Blood of Jesus and the "dower" is given at the end of the great celebration of the Marriage Supper, from the Bridegroom to the Bride. The Church will receive the "dower" at the Judgment Seat of Christ. If the type holds to the customs of ancient Israel, the Bride will be rewarded the "dower" for her faithfulness--or not, if she has not been a faithful servant--immediately following the Marriage Supper. In ancient Israel, the dower was given to help the bride to establish her home (and provide for her, if the Bridegroom died). A concubine would have had neither a bride price nor a dower.
The
ketubah (marriage contract or covenant) was drawn up and signed at the betrothal--Jesus would sign it with a pledge of His own Flesh and Blood. The
ketubah could only be broken by a divorce, by the way--the reason why Joseph would have had to divorce Mary had she been unfaithful--as Joseph had originally thought, before the angel told him the truth. The
ketubah spelled out, in detail, what each signatory would receive from the other. The Bridegroom would then go back to His Father's estate and create a place for Him to live with His Bride. It could take as long as two years. Finally, when all was in readiness, the Bridegroom's Father would give His permission for the Bridegroom to go and fetch His Bride. But, She would not know when He would come. She and her maids would need to keep watch, stay alert, be dressed and ready to go--even if He came at midnight. When the Bridegroom and His friends appeared with a shout, She would go out to meet Him. Then they would have a grand procession to the Father's estate (if at night, it would be lighted by the lamps of the Bride and her maids). There, the Bride and Bridegroom would enter the Bridal chamber and be secluded for as long as seven days. In the meanwhile, the Bridegroom's Father would throw a lavish Marriage Supper for invited guests (the Old Testament saints like Abraham, Isaac, Jacob, Moses, etc.). The Bridegroom and the Bride would re-emerge after their seclusion, and it was then that the dower would be conferred on the Bride, as the Bridegroom's gift to her.
The "dower" should not be confused with a "dowry" which is given to the Bridegroom by the Father of the Bride. It is still given today in some countries. There has recently been a great scandal in India over the "dowry murders"--where the bridegroom takes the dowry and then has the bride murdered (often through an "accident") and then do it all over again with another bride.
