What does the Bible say about the oneness of Christ with the Father?

In John 5:19, Jesus states, 'The Son can do nothing of Himself, but what He sees the Father do.' This illustrates the profound oneness between Christ and the Father, affirming that all His actions are in perfect harmony with the will of the Father. He asserts His role as the Lord of the Sabbath and the Son of God, embodying divine authority and unity with God in all things. This theological truth highlights the essence of the God-man mediator, emphasizing that Jesus, in His works and judgments, reflects the character and intent of the Father.
