He might have been attempting something, but I didn't get much past the first sentence.
Here is a chance to read it again.
Let's perform a thought experiment with Luke 18:19.
Luk 18:19
And Jesus said unto him, Why callest thou me good? none is good, save one, that is, God.
Let us just for a moment entertain the hypothesis that Christ is denying that He is good, and saying that only one Being is good, and that Being is God the Father.
We can always go back to believing that Christ IS good. A thought experiment means to entertain an idea we might not believe to be true. We might believe that because Christ is God, He has to be good. And wasn't he sinless? And did He not say that if you had seen Him you had seen the Father? Or He may be saying that speaking as a human he is not good, because humans can be tempted whereas God cannot. So we may have many doubts as to our hypothesis.
Let's try out our hypothesis viz. that Christ is not good, only the Father is.
How could this possibly be?
I previously stated that to do the will of God is "good" and to go against that will is "evil".
Both Jesus and the Father think and feel independently, and have independent wills.
We see this in the Garden of Gethsemane where Christ wills not to go through with the crucifixion, but the Father wills that he does.
Now I narrow the definition that to do the will of God THE FATHER is "good" and to go against that will is "evil".
Let's suppose Christ had refused to comply with the Father's will that He be crucified, then Christ would have been doing evil. Christ acknowledged this by saying "Father, if thou be willing, remove this cup from me: nevertheless not my will, but thine, be done".
Here Christ is denying His will and affirming the Father's will as being the one that counts.
In fact Christ is pointing us to the definition of "good". Doing the Father's will is good.
There is never a time when doing the Father's will is wrong.
Christ came to reveal "goodness".
Heb 10:7
Then said I, Lo, I come (in the volume of the book it is written of me,) to do thy will, O God.
Heb 10:9
Then said he, Lo, I come to do thy will, O God.
Christ came to set an example of doing the Father's will.
The Lord taught us to pray to the Father, not Himself.
Mat 6:9
After this manner therefore pray ye: Our Father which art in heaven, Hallowed be thy name.
Thy kingdom come. Thy will be done in earth, as it is in heaven.
The whole Lord's prayer is focused on the Father. Notice who's will is to be done, the Father's not Christ's.
Thy will be done in earth, as it is in heaven.
Let's have a look at Jas 1:13
Let no man say when he is tempted, I am tempted of God: for God cannot be tempted with evil, neither tempteth he any man:
We know that Christ could be tempted, but why is it that the Father cannot be tempted?
The Father cannot be tempted to go against His own will, just like most people are not tempted to go against themselves. Especially as James explains how God is not double minded.
I remember my Mother once saying to me "You know, your Dad is actually very easy to get along with so long as he gets his own way". I thought "toddlers are very easy to get along with so long as they get their own way". I am very easy to get along with so long as I am getting my own way.
The Father cannot sin because to sin would be to go against the Father's will, and why would the Father oppose Himself?
But every other sentient being in the universe also has a will, and when this will is in opposition to the Father, that is, by definition, "evil".
Christ learned obedience by what He suffered. Christ has not forgotten what He learned. Christ learned to conform to the Father's will, no matter what pressure to do otherwise. The Holy Spirit sent from heaven will teach us to always conform to the Father's will.
I accept the hypothesis that to do the Father's will is the definition of "good".
