Q) What about all the people before Jesus died for our sins? All the people of the old test. if they could not get to heaven by being good enough and Jesus didn’t sacrifice himself yet, that means every person born from Adam until Jesus’s death went to hell. Is this right?
Everybody who died before Jesus resurrection went to a place called Sheol. When Jesus died, many believe that He descended into Sheol to rescue the OT faithful believers. Lets look at the scriptures
What is Sheol?
In the Old Testament, Sheol is the place for the souls of the dead, both the righteous (like Jacob, Genesis 37:35, and Samuel, 1 Samuel 28:13–14) and the wicked (Psalm 31:17). In the New Testament, the Hebrew word Sheol is translated as hades, and the description of Sheol in the Old and New Testaments bears some resemblance to the Hades of Greek mythology. It is under the earth (Numbers 16:30–33), and it is like a city with gates (Isaiah 38:10) and bars (Job 17:16). It is a land of darkness, a place where shades, the shadowy souls of men, dwell (Isaiah 14:9; 26:14). It is the land of forgetfulness (Psalm 88:12), where no work is done and no wisdom exists (Ecclesiastes 9:10). Most significantly, Sheol is a place where no one praises God (Psalm 6:5; 88:10–11; 115:17; Isaiah 38:18).
In the New Testament, the most extended depiction of the afterlife is found in Luke 16:19–31. There we learn that, like the Hades of Greek mythology, the biblical Sheol has two compartments: Hades proper (where the rich man is sent, Luke 16:23) and “Abraham’s bosom” (where the angels carry Lazarus, Luke 16:22). Hades proper is a place of torment, where fire causes anguish to the souls imprisoned there. Abraham’s bosom, on the other hand, while within shouting distance of Hades, is separated from it by a great chasm (Luke 16:26), and is a place of comfort and rest.
After Christ dies He journeys to Hades, to the City of Death, and rips its gates off the hinges. He liberates Abraham, Isaac, Jacob, David, John the Baptist, and the rest of the Old Testament faithful, ransoming them from the power of Sheol (Psalm 49:15; 86:13; 89:48). They had waited there for so long, not having received what was promised, so that their spirits would be made perfect along with the saints of the new covenant (Hebrews 11:39–40; 12:23).
After his resurrection, Jesus ascends to heaven and brings the ransomed dead with him, so that now Paradise is no longer down near the place of torment, but is up in the third heaven, the highest heaven, where God dwells (2 Corinthians 12:2–4).
Now, today in these New Testament times, when the righteous die, they aren’t merely carried by angels to Abraham’s bosom; they depart to be with Christ, which is far better (Philippians 1:23). The wicked, however, remain in Hades in torment, until the final judgment, when Hades gives up the dead who dwell there, and they are judged according to their deeds, and then Death and Hades are thrown into Hell, the lake of fire (Revelation 20:13–15).
