It is He who gave to this intellectual nature free-will of such a kind, that if he wishes to forsake God his blessedness, misery should forthwith result.
Saint AugustineLord Jesus, don't let me lie when I say that I love you.....and protect me, for today I could betray you.
Saint AugustineEveryone who observes himself doubting observes a truth, and about that which he observes he is certain; therefore he is certain about a truth. Everyone therefore who doubts whether truth exists has in himself a truth on which not to doubt.... Hence one who can doubt at all ought not to doubt the existence of truth.
Saint Augustine
