Today we have one of those very short gospels at Mass which, while short, have a lot to say. Jesus explicitly proclaims his relationship with his Father; "everything has been entrusted to me." Now that means everything, not most things!
Only Jesus knows the Father and only the Father really understands who Jesus is. But then Jesus says about knowledge of the Father, "and those to whom the Son chooses to reveal him." We know the Father only because Jesus chooses to reveal him to us.
Now that's a sentence worth thinking about!
