Give her the ability to make clear decisions, to understand all she needs to know, and to be able to focus on what she needs to do. Where there is now any mental instability, impairment, or dysfunction, I speak healing in Jesus' name. May she be renewed in the spirit of her mind and have the mind of Christ.
I pray that she will so love the Lord with all her heart, all her soul and all her mind that there will be no room in her for lies of the Enemy or the clamoring of the world. May the Word of God take root in her heart and fill her mind with things that are true, noble, just, pure, lovely, of good report, virtuous, and praiseworthy. Give her an understanding that what goes into her mind becomes part of her, so that she will weigh carefully what she sees and hears.
You have said, "You will keep him in perfect peace, whose mind is stayed on You." I pray that her faith in You and Your Word will grow daily so that she will live forever in peace and soundness of mind.
