We need to be santified

Jesus said to his disciples:
‘I still have many things to say to you
but they would be too much for you now.
But when the Spirit of truth comes
he will lead you to the complete truth,
since he will not be speaking as from himself
but will say only what he has learnt;
and he will tell you of the things to come.
He will glorify me,
since all he tells you
will be taken from what is mine.
Everything the Father has is mine;
that is why I said:
All he tells you
will be taken from what is mine.’

(John 16:12-15)
