This one is straight out of the Mercy Me (Undone) songbook 
I thought I would share it since needed it on one page anyway. 
  
G5             A5                      B5     
      You put me here for a rea-son 
G5             A5                      B5     
      You have a mission for me 
G5             A5                      B5     
      You knew my name and You called it 
              G5    A5                              D5     
      Long before I learned to breathe 
 

G5                 A5         B5     
      Sometimes I feel disappointed 
                     G5  A5               B5 
      By the way  I      spend my time 
G5              A5                     B5     
      How can I further Your kingdom 
                   G5           A5                     E5     
      When I'm so wrapped up in mine 


                              D5             A5 
      In a Blink of an eye that is when 
                  E5                           G5 
      I'll be closer to You than I've ever been 
                    D5                      A5 
      Time will fly___, but until then 
                     E5                               G5 
      I'll embrace every moment I'm given 
                        E5            G5                             
      There's a rea-son I'm__ alive for a blink of an eye 
 

G5                  A5                   B5     
      And though I'm living a good life 
                   G5  A5                B5     
      Can my life be something great? 
G5          A5                      B5     
      I have to answer the question 
             G5 A5              E5  
      Before it's too late 

(Chorus) 
C5                              G5    
      If I give the very best of me 
                                     G5 
      That becomes my leg_acy 
                            D5                  G5 
      So tell me what am I waiting for? 
            E5               
      What am I waiting for? 
     

                             D5               A5 
      In a Blink of an eye that is when 
                  E5                            G5   
      I'll be clo_ser to You than I've ever been 
                    D5                 A5 
      Time will fly, but until then 
                      E5                         G5     
      I'll embrace every moment I'm given 

(Chorus)
