I haven't read the Bible for a while (I am currently rereading it), but I don't understand logic and reason from the Bible. It seems like a mash of stories/parables etc that were just kind of thrown together. But who knows,
When you read it may I recommend you pay attention to the audience of address and the timeline?
The OT is mainly about a covenant God made with Israel through Moses, hence, the Mosaic Covenant.
The OT is a typology and picture of Jesus Christ, page after page.
The NT speaks of a soon coming judgment by God on these OT people, through and through.
The NT presents many spiritual truths that have there start in the physical reality of the OT and point to Jesus. For instance, Moses foretold of a prophet like him that would come to the people (Deuteronomy 18:15-18; Acts 3:22-25).
Moses took the physical nation of Israel out of Egypt, the land of bondage, to the Promised Land.
Jesus takes His people out of spiritual bondage from sin and of this world into the New Promised Land, the heavenly country (Hebrews 11:16).
Moses was the Mediator between God and the people.
Jesus is our Mediator between the Christian and God.
Moses is the one God uses to establish a covenant with Him and the people at Mount Sinai.
Jesus is the One God used to establish a new covenant with Him and His people on the mount, outside the city.
Moses was given manna from heaven.
Jesus is the manna from heaven.
Moses lifted up the snake in the desert that all those who looked upon it would live.
Jesus was lifted up on the cross and all those who look to the cross and believe find mercy with God and live, even though they die.
Most of the people did not trust in God's means and the generation Moses led died in the desert. Only a few entered the Promised land from that generation.
Jesus, as well as the author of Hebrews, warns His/that generation that those who did not believe in Him would also perish (Matthew 23:36; Hebrews 3:8-4:11).
The NT parables relate to Israel.
