The Gift of Fear
Servile fear vs. filial fear:
To educate us in the fear of the Lord, the Holy Spirit, instead of placing before our eyes pictures of the punishment and pains due to sin, instead of representing God as a stern judge, shows Him to us as a most loving Father, infinitely desirous of our good, and He presents us the touching picture of God's favors and mercies. "I have loved thee with an everlasting love; therefore, have I drawn thee," whispers the Holy Spirit in the depths of our soul; "You are not servants, but my friends, my children" (cf. Jer 31, 3 - cf Jn 15, 15).
Captured by love for such a good Father, the soul has but one desire, to return Him love for love, to give Him pleasure and to be united with Him forever. Consequently, it fears nothing but sin, which offends God and alone can separate it from Him.
What a difference there is between this filial fear, which is the fruit of love, and servile fear, which arises from the dread of punishment! It is true that the fear of judgment and the divine punishment is salutary and in certain cases can serve greatly to hold a soul back from sin; but if it does not change gradually into filial fear, it will never be sufficient to impel the soul on to sanctity. Fear that is merely servile contracts the soul and makes it petty, whereas filial fear dilates it and spurs it on in the way of generosity and perfection.
