When we go on a unknown journey, there is fear over the journey. Life is long last journey which nobody can predict what will happen right next moment. This makes life exciting as well as fearful.
This uncertainty might lead us to God, Perfect Love. This insecure life gives us fear but it leaves us hope for love. When one goes through the darkness, there is a light driving out fear. Perfect love is like a small candle. One small candle is enough to dirve all the darkness out of our life.
