Father all-powerful and ever-loving God,
from before we were born,
your love has nurtured and sustained us.
Hear my prayer for N., my son/daughter.
Keep him/her safe in time of battle
and faithful to you, day in and day out.
Bring him/her safely home to those who love him/her.
We ask this through Christ our Lord.
