I have to respectfully disagree.
“I and My Father are one.””
John 10:30 NKJV
Jesus was fully man and also fully God. Jesus was born of a virgin through the miraculous work of God.
“I am the Alpha and the Omega, the Beginning and the End, the First and the Last.””
Revelation 22:13 NKJV
He always existed just like God the father because they are one and the same.
I and My Father are one is meant in the sense that the slave does What his Master Wills him to do.
How can somebody be fully one thing and fully another thing. It's either one or the other. Something that's born, just like you and me, cannot in any way be equal to The Being that Always Existed.
The Alpha and the Omega, the Beginning and the End, the First and the Last Pertains To The Almighty Alone. If anything, you cannot describe Something Who's Both First and Last at the same time. That Only Applies To God Almighty, The Source of every Quintessential Attribute or Quality.
Jesus did not always exist. The fact that he took birth itself alludes to the fact that his existence started with the virgin Mary's miraculous pregnancy. The latter is no less miraculous than the beginning of creation, where everything got Created out of
nothing by The Simple Command of God Almighty, 'Be', and everything simply became.
On that note, i will cite
Mark 10: 18,
"Why do you call me good?" Jesus answered. "No one is good--except God alone."
I think this is quite simple to understand. Everybody can understand this, right? And don't go into metaphorical and illogical explanations with me, will ya?
Jesus resented being called good since he clearly had insight into people not recognizing The Almighty Who's Responsible for each and everybody at each and every second. So why do you even have to call anybody good? Simply because nobody is good on their own. If somebody has goodness in him/her, it is only through God's Mercy and Benevolence. Only God Is Good Since He's The Source of every goodness. To put it in even simpler terms, try being conscious that everything that's existing at every place and every time (past, present, and/or future) already exists in God's Sight. And that nothing can be any thing except by His Will. Nothing exists unless He Wills.
