Who is the One mighty in battle? The Rock of Ages is strong on our behalf. One will put a thousand to flight. Therefore we will not live in fear. Our hearts will be in peace because we are children of the Most High God.  John 1:12.
A personal prayer: "Father, give me peace in my heart as I trust that You have sent your angels to minister around me that You assigned to protect and help me in everything that I do on earth for Your Glory."  Praise God!
