How do we know Jesus is God based on the Old Testament?

The identity of Jesus as God can be affirmed through His fulfillment of the divine roles attributed to God in the Old Testament. For example, Jesus declares Himself as 'the Good Shepherd' (John 10:11), aligning with how God is depicted in Psalm 23:1, wherein the Lord is described as our shepherd. Additionally, He claims to be 'the Bread of Life' (John 6:35), a role initially fulfilled by God's provision of manna in the wilderness (Exodus 16:4). Each of these statements demonstrates that Jesus embodies the attributes and functions of God, offering spiritual nourishment, guidance, and salvation, which further legitimizes His claim to divinity as the same 'I Am' revealed to Moses.
