Yes, almost all of them. They never talk about purgatory and hell without talking of heaven
They hope for heaven
St. Therese of Lisieux, Story of a soul, constantly talked and longed for heaven
St. Faustina, Divine Mercy in my soul, talks about heaven in her soul, that is Jesus himself
St. Anthony mary Claret, talks about how to save souls, and lead them to heaven, save them from hell.

we can imitate them, be holy, and attain heaven as well.
I imitate them in weekly confession and daily communion, and my life has changed dramatically.
There is no one that can guide you in your spiritual life better than the saints, when we read their works, they will aflame us with the fire of love of God, and set our lives in the right direction, that is to heaven
