Grace, means of

an expression not used in Scripture, but employed (1) to denote
those institutions ordained by God to be the ordinary channels
of grace to the souls of men. These are the Word, Sacraments,
and Prayer.

(2.) But in popular language the expression is used in a wider
sense to denote those exercises in which we engage for the
purpose of obtaining spiritual blessing; as hearing the gospel,
reading the Word, meditation, self-examination, Christian
conversation, etc.
