I'm no expert but its the way we were taught it in school that they're the same "person"
like this :
Is Jesus God?
Some say Jesus Christ was just a man, or maybe a great teacher. But He was and is much more than that. The Bible says Jesus is unique in both His person and His purpose. He wasn’t just some spiritual individual during His time on earth; He was both God’s Son (John 3:16) and God Himself—God in human flesh (I Timothy 3:16). Yes, He was fully man, but He was also fully God (Colossians 2:9).
The claims
Jesus claimed to be God. It might be hard to understand how this could be true, but it’s important to remember that God is much bigger and more powerful than we can comprehend. We do know that Jesus said He existed before Abraham (John 8:58). He claimed that He and His Father are one (John 10:30), and that He is equal with the Father (John 5:17-18).
Not only did He claim to be God, but He also claimed to have the power of God. He said He has the authority to judge the nations (Matthew 25:31-46). He claims the authority to raise people from the dead (John 5:25-29) and to forgive sins (Mark 2:5-7)—things only God can do (I Samuel 2:6; Isaiah 43:25).
Further, Jesus says He has the power to answer prayers (John 14:13-14), and that He will be with His followers always (Matthew 28:20). The New Testament equates Jesus to the creator of the universe (John 1:3), and in John 16:15, He says, “All that belongs to the Father is mine.”
