How do we know that Christ's heart can be enlarged?

The concept of Christ's heart being 'enlarged' is biblically illustrated through anthropomorphic language that relates divine attributes to human experiences. In Psalm 119:32, the desire for an enlarged heart reflects the fullness of His love towards His people. When God rewards Christ for His obedience with an enlarged heart, it symbolizes the infinite capacity Christ possesses to love His bride, the Church, as evidenced in Isaiah 60:1-3 where His glory is manifested to the nations. This metaphorical enlargement indicates a deep and abiding love that encompasses all His chosen ones.
