Fear is like the monster under my kids’ beds — its power is fueled not by what’s really there, but by what might be, what we imagine could be. Fear is a hollow darkness in the future that reaches back through time to rob our joy now by belittling the sovereign goodness of God.

But if we are in Christ, if we cling to him by faith, we don’t have to fear. Really, we don’t.

John Piper explains why in a 2001 letter he wrote to the people of Bethlehem. The point of the letter is to highlight several promises in the Bible that we can remember when the temptation of fear assaults us.
