God in Trinity means God in three persons which means
- God the Father
- God the son
- God the Holy Spirit
This is often confused that they are different persons and work out of hand with each other but that's wrong they are all one God in one.
I concur with this path of the author which is stated as follows:
"Jesus Christ was no less God on earth when going to His Father in paradise. He was portraying how even in pure humankind it is important to have an essential supplication life so as to do His Father's will. Jesus' going to the Father was a showing of His relationship inside the Trinity and a case for us that we should depend on God through supplication for the quality and knowledge we require."
