How do we know Christ is the apple of the Father's eye?

The New Testament consistently affirms Christ's centrality to God's plan and His unique status as the Father's beloved Son. In Matthew 3:17, the Father proclaims, 'This is my beloved Son, in whom I am well pleased,' demonstrating the delight and love God has for Christ. Additionally, Isaiah 42:1 notes, 'Behold my servant, whom I uphold; mine elect, in whom my soul delighteth,' further underscoring that all the Father's desires converge in Christ. This status as the apple of the Father's eye illustrates not only Christ's worth but also the depth of the relationship between the Father and the Son, which is pivotal for our understanding of the gospel and the grace extended to us through Him.
