Untrue worries

Jesus said to his disciples:
“I tell you,
everyone who acknowledges me before others
the Son of Man will acknowledge before the angels of God.
But whoever denies me before others
will be denied before the angels of God.
“Everyone who speaks a word against the Son of Man will be forgiven,
but the one who blasphemes against the Holy Spirit
will not be forgiven.
When they take you before synagogues and before rulers and authorities,
do not worry about how or what your defense will be
or about what you are to say.
For the Holy Spirit will teach you at that moment what you should say.”
(Lk 12:8-12)
