What does the Bible say about the connection between the Old Testament and Jesus?

The Bible teaches that all the stories in the Old Testament testify of Jesus Christ. From Genesis to Malachi, each narrative, character, and element serves as a type or shadow of Christ. For instance, in Genesis, Christ is seen as the woman's seed, while in Exodus, He is represented as the Passover Lamb. This connection illustrates that God's redemptive purpose is fully centered on Christ, whom God sent to save His people from their sins, fulfilling John 17:3, which defines eternal life as knowing the only true God and Jesus Christ.
