No matter how bad we may see ourselves in our sins; if there is still life in us, there is always hope and redemption for us. We just have to ask God for forgiveness, abandon sins, love and pursue purity.

“If you say the Rosary faithfully until death, I do assure you that, in spite of the gravity of your sins “you shall receive a never fading crown of glory.” Even if you are on the brink of damnation, even if you have one foot in Hell, even if you have sold your soul to the devil as sorcerers do who practice black magic, and even if you are a heretic as obstinate as a devil, sooner or later you will be converted and will amend your life and save your soul, if—and mark well what I say—if you say the Holy Rosary devoutly every day until death for the purpose of knowing the truth and obtaining contrition and pardon for your sins.” - St. Louis de Montfort
“Let us therefore give ourselves to God with a great desire to begin to live thus, and beg Him to destroy in us the life of the world of sin, and to establish His life within us” - St John Eudes
"I tell you that you have less to suffer in following the cross than in serving the world and its pleasures." - St. John Vianney
