Luke 12:8-12 (NIV)
8 ‘I tell you, whoever publicly acknowledges me before others, the Son of Man will also acknowledge before the angels of God. 9 But whoever disowns me before others will be disowned before the angels of God. 10 And everyone who speaks a word against the Son of Man will be forgiven, but anyone who blasphemes against the Holy Spirit will not be forgiven.
11 ‘When you are brought before synagogues, rulers and authorities, do not worry about how you will defend yourselves or what you will say, 12 for the Holy Spirit will teach you at that time what you should say.’
