I heard a reminder once, stating that you ARE a light in the world. You may choose to ignore it- but in the end, it will always be discovered. Why? Because in the darkness, even the smallest little flicker of light becomes radiant. So rather than hiding it, why not allow it's glow to guide the way for yourself and others? In the end- you will shine, regardless.
Revelation 21:4 New King James Version (NKJV) And God will wipe away every tear from their eyes; there shall be no more death, nor sorrow, nor crying. There shall be no more pain, for the former things have passed away.
