You may be going through a trial so overwhelming that it's borderline unbearable. You want to see the end of the tunnel. Which is only natural, because once we see that little speck of light, we feel we can make it through to the finish. But God's tunnels are often twisting, too complex and dark to see the light for many days. In such settings He says, "In that dark, twisting, seemingly endless period of time, trust Me. Stop running scared! Stop fearing!"
