Keep your prayers secret. Keep them between you and God. No one needs to know what you are praying. No one needs to know that you are praying on their behalf. There is no need to tell everyone on a social website, or in a church, or anywhere else that you are praying. Just do it. Pray whatever you want to pray. Keep it between you and God.
Oh, and another thing! When a person enjoys a good experience, there's no need for you to say anything like, "I've been praying for you."
Pray whatever you want. Do it in secret. Leave it alone.
