When God calls us to fulfill some mission, who is at work? God or us? The truth is that we are both at work, God is the source and we are the instrument. We make a freewill effort, but it is God who shines through. Just as a window can act as a source of light in the house, it is not the window that shines, it is the Sun. Similarly, we must surrender ourselves to God so that He will shine through us, but we must always remember that we are only a window through which God will shine in our world (See Diary #438).
Do you want God to shine through you brightly? Do you want His rays of love to radiate and enlighten others? If you do, then humble yourself so that you can become His instrument of grace. Recognize that you are nothing more than an instrument, not the source. Be open to the Source of all Grace and He will shine through with great power and splendor.
Lord, I offer myself to You as a window for Your merciful Heart. Shine through me, dear Lord. May I be a true instrument of Your grace and may I always remember that You and You alone are the source of all grace and Mercy. Jesus, I trust in You.
