Saint Teresa, as the Roman Rota attests, never fell into any mortal sin; but still Our Lord showed her the place prepared for her in Hell; not because she deserved Hell, but because, had she not risen from the state of lukewarmness in which she lived, she would in the end have lost the grace of God and been damned.
Alphonsus LiguoriDevil does not bring sinners to Hell with their eyes open: he first blinds them with the malice of their own sins. He thus leads them to eternal perdition. Before we fall into sin, the enemy labours to blind us, that we may not see the evil we do, and the ruin we bring upon ourselves by offending God. After we commit sin, he seeks to make us dumb, that, through shame, we may conceal our guilt in confession.
Alphonsus LiguoriLet us, at any rate, give heed to suffer joyfully the crosses that God sends us, because they all, if we are saved, will become for us eternal joys. When infirmities, pains, or any adversities afflict us, let us lift up our eyes to heaven and say, "One day all these pains will have an end, and after them I hope to enjoy God forever."
Alphonsus LiguoriHow, then, shall God give himself entirely to that one who, besides his God, loves creatures still?
Alphonsus Liguori
