Do the people in the Old Testament get to go to heaven if Jesus hadn't died for them?

Ever since “the fall,” salvation has always been available through God. The requirement for salvation has always been faith. The object of faith for salvation has always been God. In the Old Testament it was God the Father; in the New Testament it is Jesus Christ, His Son. No one, either before Jesus’ death or since Jesus’ death, would ever be saved without the resurrection of Jesus. His death paid the penalty for past sins of Old Testament saints and future sins of New Testament believers.

Do you remember the account of Abraham? In Genesis 15:6, Abraham believed in the Lord and was credited for being righteous. He was “saved” because he believed and trusted in God and God saw him as righteous, meaning right – not wrong- according to His eyes. In Isaiah 69:10, Isaiah says, “I delight greatly in the Lord: my soul rejoices in my God. For He has clothed me garments of salvation and arrayed me in a robe of His righteousness…” Isaiah’s faith in god made him righteous and “saved.” Even King David, in Psalm 86:1-2, cried out to the Lord and was saved through his faith. There are plenty of other Old Testament heroes that are saved through the simple act of having faith in God (By faith, Abel…by faith, Enoch…by faith, Noah…by faith, Sarah…by faith, Isaac… by faith, Jacob…by faith, Joseph…by faith, Moses…by faith, Rahab…etc.)

And, to answer your question directly, all the Old Testament believers who followed Abraham in his faith in God and also had faith in God also enjoy eternity with Jesus. Ephesians 2:8 states, “For it is by grace you have saved, through faith – and this is not from yourselves, it is a gift of God.”
