God's forebearance

I get worked up over big and small offenses of others. I'm especially hard on liturgical abuse, which, to me, is sacriligious. Then I read Gospel passages like this:

"Amen, I say to you, all sins and all blasphemies that people utter will be forgiven them. But whoever blasphemes against the holy Spirit will never have forgiveness, but is guilty of an everlasting sin." (Mk. 3:28-29)

It seems that Jesus is pretty tolerant of our lack of reverence. Note, he says such sins will be forgiven. There is nothing conditional about it. It seems that the only sin that can really condemn you is this sin against the Holy Spirit. According to the footnote that is to attribute to the Devil what is actually from God. Hm.
