Exegesis

The structure of the verse provides a rich ground for exploration. Jesus begins with the declaration of God’s name, which signifies God's attributes, character, and the very essence of His being. The name embodies His authority and His eternal purpose.

• “That the love wherewith thou hast loved me”: This phrase introduces the central theme of divine love. The love of God, demonstrated in Jesus, is to be internalized within the believers. Albert Barnes highlights that this love is transformational, shaping the identity and mission of believers.
