Here is a sample prayer for a friend that you can use as a guide:
Dear God,
I lift up my friend to you today. Please be with them and fill them with your love and peace.
I pray that you would meet their needs and bring them your strength and comfort. Please give them wisdom and guidance as they face the challenges in their life.
Help them to feel your presence and know that they are never alone. May they experience your love and grace in a deep and personal way.
Please bless my friend and keep them safe. In your holy name I pray, Amen.
