As is true of all Scripture, God intends that this story – a story of His saving grace poured out freely on needy humans – should become our story as well.
For indeed, this is the story of all who follow Christ. For Christians, personal salvation is very similar to the story of the Pentateuch. God, the Sovereign of the universe, breaks into our personal history and provides a solution for our brokenness. Because of His love and grace, He provides salvation by His own revelation in history (incarnation). God gives us prophets and teachers to interpret his historical acts and help us maintain our relationship with Him. The rest of the story is one of growth in grace, or the imitation of our Saviour. So the gospel of Jesus Christ was also the gospel of the Israelites.
