From before time as we know it began, a plan was set in motion by God, the Creator of all things (Genesis 1-3.)
God is love. God created you. God loves you.
Rebellion against God, by a person we can all trace our lineage to (Adam) changed the status and destiny we were born into (Genesis 3.)
A physical body created perfect and holy, alive spiritually and connected to God, designed to live forever with Him in paradise, entered into a continuous state of death that began with spiritual death (complete separation from God), continuing throughout life as a gradual degradation of the body, and culminating in physical death.
Those who sleep in the dust of the earth will awaken, some for eternal life [heaven], and some for disgrace, for eternal abhorrence [hell] (Daniel 12:2.) Isaiah 66:24 also talks about hell “And they shall go out and see the corpses of the people who rebelled against Me, for their worm shall not die, and their fire shall not be quenched, and they shall be an abhorring for all flesh.”
Abram believed in the Lord, and He accounted it to him as righteousness, salvation by faith, prior to the Mosaic Law (Genesis 15:6.)
The Law was given to make us conscious of sin. It did not contain the power to save anyone (Habakkuk 2:4.)
To temporarily reconnect us with God, He required sacrifices, almost all involving shed blood, in order to provide atonement, temporary covering over the sin (Leviticus 4, Leviticus 16, Numbers 15, Deuteronomy 12.) When the temple altar was destroyed, God ended the animal sacrifices.
God made it clear that He would be forming a new covenant with a new heart and His spirit placed within us (Jeremiah 31:30-33 Tanakh [Jeremiah 31:31-34 OT], Jeremiah 32:37-40, Jeremiah 33:14-16, Ezekiel 16:58-63, Ezekiel 36:26-29, Ezekiel 37:21-26, Isaiah 55:3-8.)
Isaiah 53. “Despised and rejected by men, wounded because of our transgressions (our rebellion) crushed because of our iniquities (our depravity [moral corruption, wickedness); the chastisement of our welfare was upon him, and with His wound we were healed (spiritual healing/healing from sin Psalm 6, Psalm 41, Psalm 103)
We all went astray like sheep, we have turned, each one on his way, and the Lord accepted his prayers for the iniquity of all of us. He was oppressed, and he was afflicted, yet he would not open his mouth; like a lamb to the slaughter he would be brought, He committed no violence, and there was no deceit in his mouth. He poured out his soul to death, and with transgressors he was counted; and he bore the sin of many, and interceded for the transgressors.”
The saving death of the Messiah is the final atonement, for it is the propitiation, the quenching of God’s wrath for us when He completely removed our sins and took them upon Himself (expiation.) Our entire body of sin was imputed onto Him (assignment of a value/placed) and His righteousness was imputed onto us (double imputation.)
Over 300 prophecies stated in the Tanakh (Tanach/Hebrew Bible/Old Testament) were fulfilled by one named Jesus.
Our eternal God became man (incarnation) for our salvation; sinless, born under the Law, to fulfill the Law perfectly (Genesis 49:10.)
By faith, we are able to be reconciled to God forever. Just as Abram back in Genesis 15, by faith.
This is the gospel, the good news!
