Almighty and merciful
you give your faithful people
the grace that makes every path of this life
the straight and narrow way which leads to life eternal.
Grant that we,
who know that we have no strength to help ourselves,
put all our trust in your almighty power,
and by the assistance of your heavenly grace,
always prevail in all things,
against whatever arises to fight against us;
through Jesus Christ our Lord. Amen.
