Some commentaries can be useful, to gently turn our attention to what only we can do ourselves, in ourself. Where did the commentators get their words?
God being 'our Father', 'the Christ' -- being with us always, -- do we need a mediator, 'another'? Yes, in the beginning, until we see where we are trapped in in our personal attention, interest, belief and identity.
The character Jesus says: "Nevertheless I tell you the truth; It is expedient for you that I go away: for if I go not away, the Comforter will not come unto you; but if I depart, I will send him unto you."
“Look, an hour is coming and has already come when you will be scattered, each to his own home, and you will leave Me all alone. Yet I am not alone, because the Father is with Me. 33I have told you these things so that in Me you may have peace. In the world you will have tribulation. But take courage; I have overcome the world!”
'in Me' you may have peace ... where is this 'in Me'? Is it a fleeting mood, a fickle thought, an opinion, a guess, a physical location, something in an assumed future, a childhood memory?
'In the world you will have tribulation' ... certainly; what is the world? Is the world circumstances, or our attitude? Like little children, know your words and don't be afraid to ask: 'ask and ye shall receive'.
Truth is an activity in our own consciousness; truth is not the 'right' answer, but knowing beyond doubt, knowing beyond our conditioned thinking mind; intuitively, effortlessly.
