Consider seriously how quickly people change, and how little trust is to be had in them; and hold fast to God, Who does not change.
Teresa of AvilaIf we do not use great care to mortify our will, there are many things which can deprives us of the holy freedom of spirit that we are seeking in order to fly more freely to our Creator, without always being bogged down with the clay of this earth. Moreover, there can never be solid virtue in a soul that is attached to its own will.
Teresa of AvilaAnyone who has the habit of speaking before God's majesty as if he were speaking to a slave, careless about how he is speaking, and saying whatever comes into his head and whatever he's learned from saying prayers at other times, in my opinion is not praying. Please, God, may no Christian pray in this way.
