How do we know that Jesus is one with the Father?

In John 14:9, Jesus reveals the profound truth of His divine nature by stating, 'He that hath seen me hath seen the Father.' This assertion underscores the reality that Jesus is the perfect representation of the Father, embodying His nature, character, and purpose. Throughout Scripture, we see that Jesus performs miracles that testify to His divinity, further confirming His oneness with the Father. Such unity is essential to understanding the doctrine of the Trinity and reflects the perfect harmony in the redemptive work accomplished in Christ.
