Many things in life can make us fearful. Whether it is the fate of our livelihood, the fate of our children, the fate of our people in Israel, or the fate of the world. When our faith is placed solely in Hashem, we need not fear.
Rebbe Nachman says "כל העולם כולו גשר צר מאד והעיקר לא לפחד כלל" - the whole world is a narrow bridge, and the main thing is not to fear at all. When we know Hashem is taking care of us and protecting us we can truly place our trust completely in Him and face our challenges with confidence.
