Luke 12:8-10

“I say to you, whoever declares openly and confesses Me before men [speaking freely of Me as his Lord], the Son of Man also will declare openly and confess him [as one of His own] before the angels of God. But he who denies Me before men will be denied in the presence of the angels of God. And everyone who speaks a word against the Son of Man, it will be forgiven him; but he who blasphemes against the Holy Spirit [that is, whoever intentionally discredits the Holy Spirit by attributing the authenticating miracles done by Me to Satan], it will not be forgiven him [for him there is no forgiveness]. [Matt 12:31; Mark 3:28-30]
