This "greatest sin" is blasphemy against the Holy Spirit. But what exactly is that? Have I committed it without realizing it?
Imagine how relieved I was to read in "I Believe in Love" that this sin is 'through despair and pride, refusing mercy.'
Father d’Elbée writes that Judas would have been forgiven for betraying Jesus, if only he'd believed in His infinite love and desire to forgive him. But instead, Judas despaired or was maybe too proud to humble himself and ask for forgiveness.
The wonderful news is that as long as we believe, we can be forgiven. If we place ourselves humbly before Christ - Who went to the enormous lengths of dying so that we could be forgiven - and ask for it, we shall be granted that mercy.
The worst thing we can do is throw Jesus' sacrifice back in His face by refusing to accept His gift of forgiveness.
Isn't it good to know how simple it is to avoid the greatest sin of them all?
