Another Valley Left Behind

I don't understand this trial
 I've never walked this road before
 If one more step or many miles
 I'll just have to trust you Lord
 For there is nothing left behind me
 That I could go back to
 It's my desire to make this journey
 So by your grace I'll make it through
 Chorus:
 Through the storms and through the trials
 Across the desert's burning sand
 You have said that you'd go with me
 And give me strength to stand
 Through the weeping in the darkness
 When the morning sun does shine
 I'll have my time of joy and gladness
 Another valley left behind
 I can' see a silver lining
 Behind the clouds hanging o'er
 And I can't seem to find the answers
 To my questions anymore
 You never promised me exemption
 From the testing times of life
 But I sure need some light for traveling
 Cause Lord it sure looks dark tonight
