Why is the Torah (Covenant of Law) inferior to the New Covenant of Grace? (Hebrews 8:7)
When you seek forgiveness and righteousness through the Hebrew Scriptures, remember that mankind was made “right” with God by faith, alone (Hebrews 11)…repentance is good and necessary for salvation (Luke 13:3) but remember that there was no eternal atonement for sin in the Hebrew Scriptures (Hebrews 10:4) and this made relevant the place of the dead known as Sheol where the faithful in God awaited the blood atonement of Messiah Jesus (Luke 16; Psalm 16:10).
Yes, one could experience righteousness (a right standing) before God in the Hebrew Scriptures by “faith” as demonstrated by Enoch, Abraham, David (Hebrews 11), but their sin had not received the atonement; therefore, they awaited Messiah in Sheol (the place of the dead) because nothing impure is permitted to enter the Kingdom of God (Psalm 16:10; Revelation 21:27) and this is why the Kingdom of God/Heaven is almost completely absent in the Hebrew Scriptures…it was not relevant for mankind at that time but has become relevant with the New Covenant and the revelation of Jesus Christ and His blood atonement for sin (2 Corinthians 5:8; Matthew 26:28); therefore, Sheol/Hades for the righteous dead in body is no longer relevant as those who die in Jesus Christ are instantaneously ushered into the presence of God (Psalm 16:10; 2 Corinthians 5:8; John 11:17-44).
If you die in Torah you will die the “second death” in Perdition because you have rejected the atoning blood sacrifice of Messiah Jesus and you will die in your sin (John 8:24). Trusting – believing that Jesus Christ died to pay your sin-debt is the only Way to the Father and eternal life (John 14:6).
