Lord Jesus Christ,
you have come to comfort and save all troubled souls.
Come also to me and stay with me in my distress.
Fill my troubled heart with the Word of your promise,
“I am with you always.”
Fill my home with your blessing,
and my whole life with Christian humility.

“Fill my troubled heart with the Word of your promise, ‘I am with you always.'” in the original is “Fill my miserable heart with the beauties of Thy comforting presence…”
Father of all mercies and giver of all comfort:
deal graciously, we pray, with those who mourn,
that, casting all their care on you,
they may know the consolation of your love;
through Jesus Christ our Lord.

Almighty God, Father of all mercies and giver of all comfort,
grant that in all our grief we may turn to you,
and because our need is beyond any human help,
grant us the peace of your comfort and the strength of your love;
through Jesus Christ our Lord. Amen.
