"And every one who speaks a word against the Son of Man will be forgiven; but he who blasphemes against the Holy Spirit will not be forgiven."
A few weeks ago I was wondering about that bible verse and what it meant and now I got the answer. I watched Mother Angelica's video and one caller in her program asked that question and now I know what it means. She said it's about a person who despairs, who thinks that his sins are greater than the mercy of God, who does not ask for forgiveness and does not repent. Presumption is also a sin, thinking that you can sin all you want coz God is merciful.
