If we do not say something with our mouths and think something different, then...

If the Lord sees that we pray the "Our Father" perfectly, without pretension, and that we are determined to carry out what we say, He will enrich us with His gifts, for He is very pleased when we engage with Him honestly, sincerely, and uprightly. And if we do not say something with our lips while thinking something else, He will always give us more than we ask for.

(Teresa of Jesus, The Way of Perfection XXXVII,4)
