God already knows our needs. He knows our hearts. He knows the outcome, but He still commands us to pray. Once or twice I have been awakened with a really strong impression, "Pray for this person.' So strong a message that I pray. I do not know 'why' I prayed sometimes, but the impression was so strong that I did.
Others have the same experience as in the following testimony my daughter shared with me.
The single woman who had her own business assessing properties felt the economic impact of the last few years. Few people called her with requests to have assessments done. In fact from November through March she had only two assessments. She sought work otherwise to hold her over, but was considering filing for bankruptcy.
As she walked her dog in the park one morning a young woman came up to her. "God told me to go to the park this morning and to pray with, pray for the woman with a dog. You are the only woman here with a dog, so I must be supposed to pray for you." She prayed for the business woman's needs and crisis and then left the park. No names exchanged as far as I can tell.
Within 24 hours the struggling business woman had 10 phone calls for assessments. After five months with only 2, she could only know that this had to be of God.
I was told of this God mandated personal prayer time from my daughter who is related to the woman. Because the woman has also struggled with her beliefs, I am praying it is a turning point for her faith to be deepened and her own prayer life to grow.
