Brethren and sisters, we have nothing to fear if we stay on the Lord’s side. If we will be prayerful, seeking wisdom from God, who is the source of all true wisdom; if we will cultivate a spirit of love and peace and harmony in our homes; if we will reach out to our neighbors and others in a spirit of Christian love and appreciation, helping those in distress wherever we may find them; if we will be honest with the Lord in the payment of our tithes and offerings, we shall be blessed as God has promised. Our Father has made explicit covenants with his people. He is in a position to keep those covenants. It is my testimony that he does so.
Then Elder Gordon B. Hinckley, "Fear Not to Do Good", General Conference, April 1983
This world can be a scary place. But we don't need to be afraid. Easier said than done, I know.
All we can do is stay close to the Lord. That's it. It's that simple but harder than we realize sometimes.
