"Do not be afraid"

One night while Paul was in Corinth, the Lord said to him in a vision,
"Do not be afraid.
Go on speaking, and do not be silent, for I am with you.
No one will attack and harm you,
for I have many people in this city."
He settled there for a year and a half
and taught the word of God among them.

-- Acts 18:9-18

The practice of the moral life animated by charity gives to the Christian the spiritual freedom of the children of God. He no longer stands before God as a slave, in servile fear, or as a mercenary looking for wages, but as a son responding to the love of him who "first loved us":

If we turn away from evil out of fear of punishment, we are in the position of slaves. If we pursue the enticement of wages, . . . we resemble mercenaries. Finally if we obey for the sake of the good itself and out of love for him who commands . . . we are in the position of children.

-- CCC 1828
