From the book "Preparation For Death" by St. Alphonsus Maria de Liguori, Bishop and Doctor of the Church:
"To accept death in order that the will of God may be fulfilled, merits for us a reward similar to that of the martyrs, because they accepted death to please God. He who dies in union with the will of God makes a holy death; and the more closely he is united to it, the more holy death he dies. The Venerable Blosius declares that an act of perfect conformity to the will of God at the hour of death not only delivers us from Hell but also from Purgatory."

Saint Therese said that we would offend God if we didn't trust enough that we would get to heaven right after dying.

Saint Therese to her novices:
"Oh! How you grieve me! You do a great injury to God in believing you're going to Purgatory. When we love, we can't go there....It is true that God will judge us at one point, but He is always and first our Father Who... suffers when He has to punish His child and sees its suffering....And this really means that God does not want Purgatory!"
