I kneel down before you to ask for your mercy and grace on my son, whose life is threatened by a malignant brain tumor. I pray that you will rebuke the tumors so they will stop growing. Lord, I lay down my child before you. Please put your hand on his head and let me tumors die, and let the enemy leave. May your healing rays penetrate his brain, and may we praise your name forever. In the name of Christ Jesus I pray.
