Praying from Matthew 8:16 relating to Healing, Deliverance, Authority

Lord Jesus, as evening comes, I bring to you all those who are possessed with demons. I claim the promise that you will cast out the spirits with a word and heal all who are sick. I trust in your power and authority over all evil and sickness. Thank you for your love and mercy towards us. In your holy name, I pray. Amen.

Verse: When evening came, they brought to him many possessed with demons. He cast out the spirits with a word, and healed all who were sick,
Matthew 8:16

This is a Promise. The verse describes Jesus casting out demons and healing the sick, but does not contain a command for the reader to follow.
