John 8:28 I do nothing of myself

Then said Jesus unto them, When ye have lifted up the Son of man, then shall ye know that I am he, and that I do nothing of myself; but as my Father hath taught me, I speak these things. -John 8:28 Bible, King James Version

Individual I AM Presence

The Beloved Messenger teaches us: "It is so important... to hold the Great Calm Realization of the Assisting Host of Ascended Masters... It is necessary to train the outer self to remember always in whatever you do, that It is the Sacred Fire doing these things, and not the physical form... Jesus constantly reminded the people- "I of Myself can do nothing. It is the Father Within that doeth the Works." ('The Voice of the I AM' December 1946 p14-15) 

When Jesus spoke of His Father in Heaven He was referring to His Higher Self or I AM Presence.

The Aquarian Gospel of Jesus the Christ by Levi H. Dowling

CHAPTER 8.

Elihu’s lessons to Jesus' mother in Egypt

¹Again Elihu met his pupils in the sacred grove and said,
⁵There are two selfs; the higher and the lower self.
⁶The higher self is human spirit clothed with soul, made in the form of God.
⁷The lower self, the carnal self, the body of desires, is a reflexion of the higher self, distorted by the murky ethers of the flesh.
⁸The lower self is an illusion, and will pass away; the higher self is God in man, and will not pass away.
⁹The higher self is the embodi­ment of truth; the lower self is truth reversed, and so is falsehood manifest.
¹⁰The higher self is justice, mercy, love and right; the lower self is what the higher self is not.
¹¹The lower self breeds hatred, slander, lewdness, murders, theft, and everything that harms; the higher self is mother of the virtues and the harmonies of life.
¹²The lower self is rich in prom­ises, but poor in blessedness and peace; it offers pleasure, joy and sat­isfying gains; but gives unrest and misery and death.
¹³It gives men apples that are lovely to the eye and pleasant to the smell; their cores are full of bit­terness and gall.
¹⁴If you would ask me what to study I would say, yourselfs; and when you well had studied them, and then would ask me what to study next, I would reply, your­selfs.
¹⁵He who knows well his lower self, knows the illusions of the world, knows of the things that pass away; and he who knows his higher self, knows God; knows well the things that cannot pass away.
¹⁶Thrice blessed is the man who has made purity and love his very own; he has been ransomed from the perils of the lower self and is himself his higher self.
