The Gospel of Jesus Christ is the expression of God's loving compassion and graceful forgiveness to a dying world. It is the story of the Son's death, burial, and resurrection, as well as the promise of His return. It is "the Power of God for Salvation to all those who believe."
The Gospel states that Man was created in God's image, in a state of perfect union with Him. However, Man rebelled against that union, choosing instead to seek knowledge apart from God's provision. This resulted in a cessation of the unity between Creator and Created, and a divide was formed between Man and God.
On his own, Man is unable to bridge that gap by any action or inaction, since the fallen nature is applied *a priori* from birth. The natural and necessary result of this depraved nature is eternal separation from God. Only the sacrifice of a perfect Savior could pay this debt and restore unity with the creator.
God, born as a man, but being without the depravity of Man, came to Earth and died at the hands of men in order to serve as that perfect sacrifice. Upon His death, He was temporarily separated from the unity that existed within the three persons of God. But Death was unable to hold Him for long. The Son was raised up and rejoined the Father. This act — the only thing that cost God anything, and which cost Him everything — resulted in the subjugation of Death, and was sufficient payment of Man’s debt.
For those who accept Him as Lord and believe in His Salvation, Jesus’ blood covers them, and His righteousness is imputed to them. When God looks down on the Saint, He sees only the blood of Christ. As a sign and a seal of their Salvation, the soul of the Saint is indwelled by the Holy Spirit, who interprets the prayers of the Saint, counsels and edifies the Believer, and empowers and equips them for every good work.
At some future date, the Son will return to Earth. The Saints will be raptured into Glory, and will once again live in perfect Unity with God for eternity. Those who refused to accept the gift of Salvation will be banished from His presence, and spend eternity separated from Him.
