How do we know that Moses wrote about Christ?

In John 5:46, Jesus affirms that Moses wrote about Him, asserting that the Scriptures bear witness to His identity and mission. For instance, the account of creation in Genesis illustrates God's intention behind humanity's existence and hints at the future redemption in Christ (Genesis 1:26-27). Additionally, the promise in Genesis 3:15 foretells of a Savior who will conquer sin, highlighting the necessity of Christ’s redemptive work. The sacrificial typology seen in Genesis 22, where God provides a ram in place of Isaac, directly points to Christ as the ultimate sacrificial Lamb, affirming that Moses, inspired by the Holy Spirit, wrote these truths to prepare hearts for the Messiah.
