Your word is a lamp for my feet, a light on my path. Psalms 119:105 NIV
We live in a world of spiritual darkness. How can we find our way around? Our light comes from the Word of God. It illuminates the way so we can walk safely through the spiritual darkness of this world. The Word of God keeps us from stumbling.
We also have the prophetic message as something completely reliable, and you will do well to pay attention to it, as to a light shining in a dark place, until the day dawns and the morning star rises in your hearts. 2 Peter 1:19 NIV
