For Assistance in Temptation

Almighty and merciful God, who dost grant unto Thy faithful people the
grace to make every path of life temporal, the strait and narrow way
which leadeth unto life eternal, grant that we, who know that we have no
strength as of ourselves to help ourselves, and therefore do put all our
trust in Thine almighty power, may, by the assistance of Thy heavenly
grace, always prevail in all things, against whatsoever shall arise to
fight against us; through Jesus Christ our Lord. Amen.

“Roman Breviary
