Heavenly Father,
I come before you with a heavy heart, seeking your divine intervention and healing touch for my son who is suffering from a very bad cough. You are the ultimate healer, and I believe in the power of your love and compassion.
Please, Lord, look upon my son with mercy and grace. Heal his body, soothe his throat, and ease his breathing. Remove this cough that torments him, and restore his health and vitality.
I pray with all my heart, in desperation and longing, knowing that with you, all things are possible. Strengthen my son's immune system, protect him from further illness, and bless him with wellness and strength.
In your infinite wisdom and kindness, hear my prayer and grant healing to my beloved son. I trust in your love and mercy, now and always.
Amen.
