Why did Elohim institute animal “blood sacrifices” under the Levitical Law given Israel’s children?

Animal blood sacrifices could never take away sin (Hebrews 10:4) but their purpose was two-fold:

1) The blood of animals, first exemplified in Genesis 3:21 following Adam’s compromise with evil and later enacted through Levitical Law as per Leviticus 17:11, foreshadowed the only acceptable atoning sacrifice for the sins of humanity; that is, the sinless blood of Jesus our Messiah shed at Golgotha which initiated the New Covenant and provided forgiveness of sin by New Covenant promise actuated by faith (Matthew 26:28; 1 Peter 1:18-19; Hebrews 8:12; John 3:16).

2) From the beginning, “faith” has been the KEY to Elohim’s heart (Hebrews 11); that is, believing that Elohim is true and will do exactly as He has promised in His spoken and written words. It was NOT the blood sacrifice offered by the children of Israel that made one righteous or “right” with Elohim (Hebrews 10:4) but it was the “faith” of the one offering the sacrifice that engendered covenant righteousness (a right standing) with the Father.

With that said, those in the Old Testament who were made right with Elohim through faith were not permitted to enter Elohim’s presence in the Kingdom as the acceptable atonement via Messiah had not yet manifest as “nothing impure will ever enter therein” (Revelation 21:27); therefore, Old Testament saints were detained in Sheol-Paradise awaiting Messiah’s atonement and were subsequently escorted into the Kingdom by Messiah while His body of flesh lie in state for three-days (Luke 16; Psalm 16:10; Luke 23:43) .

In conclusion,

Torah and its laws, sacrifices, covenants, were simply a divine roadmap leading to our need for Messiah Jesus by faith; therefore, Torah was NEVER the destination as Jesus is the only Way, the only Truth, the only Path to LIFE available to humanity as Jesus is the fulfillment of all that Torah foreshadowed (John 14:6; Galatians 3:24). If one perishes in Torah, they perish in Hell in their sin; Jesus as one’s Messiah by faith is the divine Answer and the only acceptable Solution to mankind’s sin problem (Ephesians 4:7-10; Acts 4:12).
