2. Atonement by the Sacrifice of Jesus Christ

World Scripture

Since all have sinned and fall short of the glory of God, they are justified by his grace as a gift, through the redemption which is in Christ Jesus, whom God put forward as an expiation by his blood, to be received by faith. This was to show God’s righteousness, because in his divine forbearance he had passed over former sins; it was to prove at the present time that he himself is righteous and that he justifies him who has faith in Jesus.
Romans 3.23-26

But when Christ appeared as the high priest of the good things that have come, then through the greater and more perfect tent (not made with hands, that is, not of this creation) he entered once and for all into the Holy Place, taking not the blood of goats and calves but his own blood, thus securing an eternal redemption.

For if the sprinkling of defiled persons with the blood of goats and bulls and with the ashes of a heifer sanctifies for the purification of the flesh, how much more shall the blood of Christ, who through the eternal Spirit offered himself without blemish to God, purify your conscience from dead works to serve the living God.¹²
Hebrews 9.11-14

In this is love, not that we loved God but that he loved us and sent his Son to be the expiation for our sins. Beloved, if God so loved us, we also ought to love one another.
1 John 4.10-11

For it is impossible to restore again to repentance those who have once been enlightened, who have tasted the heavenly gift, and have become partakers of the Holy Spirit, and have tasted the goodness of the word of God and the powers of the age to come, if they then commit apostasy, since they crucify the Son of God on their own account and hold him up to contempt.
Hebrews 6.4-6

Teachings of Sun Myung Moon

Jesus Christ came to the earth to save humanity, bringing with him the glory, love and eternal life of God. Yet there was one condition that obstructed his way. This was none other than sin—sin intertwined like a gigantic steel net, woven through this person and that person, this organization and that organization, this society and that society, this nation and that nation. Jesus willingly offered himself to eradicate sin; otherwise we could not see the glory of God on this earth; nor could we know the love of God or the life of God.
(1:167, July 11, 1956)

When someone owes a huge debt, if the creditor displays good will in forgiving a portion of the debt, then the debtor can pay back less than the total amount and still satisfy the entire debt. The outstanding example of this is redemption through the cross. Merely by fulfilling a small indemnity condition of faith in Jesus, we receive the much greater grace of salvation, which entitles us to participate with Jesus in the same resurrection.
(Exposition of the Divine Principle, Restoration 1.1)

Many Christians believe that the omniscient, omnipotent, benevolent and loving God forgives us even though we commit sins tens of thousands of times. Then as soon as they go outside the church door they start fighting again. A church is not a house of forgiveness, dispensing forgiveness to people who commit sins unceasingly.

If God could forgive sins so lightly, why would He not forgive the one sin that was committed in the Garden of Eden? Furthermore, if God could find a way to forgive Satan, would He not have done it? Surely He would. Nevertheless, God cannot forgive Satan’s sin, which transgressed the core principle of the universe. For God to forgive that sin would be to fundamentally undermine the universal law of love, causing the world, which was created for love, to fall into chaos. Satan violated God Himself. This cannot be forgiven.

This is why God had to set up the Providence of Restoration to enable humans to reach the standard prior to the Human Fall. By this means, when people reach that standard, Satan can be expelled and a new perfect Adam can appear. It has taken God six thousand years to prepare that foundation.
(19:161, January 1, 1968)
