Jesus showed that the person who blasphemes the Holy Spirit has gone so far into sin, that such a person does not have forgiveness,

“And anyone who speaks a word against the Son of Man, it will be forgiven him; but to him who blasphemes against the Holy Spirit, it will not be forgiven” (Luke 12:10).

However, that does not mean that speaking against the Son of Man, Jesus, is a minor offense, for truly if we speak against Him, and never repent, He will not forgive us and we will lose our souls.

Let us always speak highly of the Lord and of the Spirit.
