Brazilians have a phrase to talk about someone with every advantage. They say the person has both the knife and the cheese in hand. Much like we’d say a person is in the catbird seat. Someone with the upper hand.
Jesus Christ has the Spirit without restriction, and because of this he speaks the words of the Father, from whom he has received all things. He therefore needs nothing, and owes nothing to no one.
For he whom God has sent utters the words of God, for he gives the Spirit without measure. The Father loves the Son and has given all things into his hand.
John 3:34-35 ESV
In Christ, the Father has concentrated all his effort, has delivered everything in his hands. Why, then, do people run to lesser beings to ask a blessing, to seek grace? The list of such beings is long and wouldn’t fit in a short meditation like this, but it’s worth noting that, if another figure appears on the religious radar, that religion doesn’t have God’s approval.
If Jesus has been given everything by the Father, all others are left with nothing.
