And Jesus answered and said unto him, Blessed art thou, Simon Bar-jona: for flesh and blood hath not revealed it unto thee, but my Father which is in heaven.

And he said unto him, Why callest thou me good? there is none good but one, that is, God: but if thou wilt enter into life, keep the commandments.

But very truly I tell you, it is for your good that I am going away. Unless I go away, the Advocate will not come to you; but if I go, I will send him to you. Very truly I tell you, you will weep and mourn while the world rejoices. You will grieve, but your grief will turn to joy.

Blessed art thou: for flesh and blood hath not revealed it unto thee, but my Father in heaven
And he said unto him, Why callest thou me good? there is none good but one, that is, God
Jesus was the literal son of God and only perfect being to walk the earth, yet even he urged his disciples to look higher than himself. He was stressing to them the importance of getting personally connected to the Maker, rather than trying to work through any secondary source.
Perhaps this was because Jesus spent his youth and early adult life getting to know his father before fully embracing his ministry and role as the savior (Luke 2:52). He was simply preaching what he had practiced.

It is for your good that I am going away. You will weep, but your grief will turn to joy
This next verse is very interesting. Jesus is informing his disciples that he will very soon leave this earthly realm, and he is saying that this is a good thing for them. At the time that might have seemed a very strange pronouncement, but he was able to see the bigger picture, and how much his disciples needed him to leave them.
Because while his disciples meant well, they were still using him as a crutch. This is made evident in how clueless they initially became after he did leave them. They didn’t know how to go on and tried to return to the life of lowly fishermen (John 21:3).
But as we see in the rest of their stories eventually they did reach their full maturity, and they only did it after Jesus’s ascension. They could only became the spiritual giants they were born to be after his departure, and so it truly was for their good that he was going away.
