What are the lyrics to Lanny Wolfe's 'Stirred But Not Changed'?
Often times my heart has been stirred by the things that I have heard,About so many who have never heard God's word,and though tears would fill my eyes all to soonI'd realize though my hearts been stirred my life has not been changed.Chorus:I'm so tired of being stirred about the lost who need to hear.I'm so tired of being stirred that His coming is so near;I'm so tired of being stirred till I cry bitter tears.I'm so tired of being stirred but not being changed."Have I heard it for so long that He's just another song?Has the story lost its thrill that I once knew?Lord, give me a burden that's so strong,That it will last when my tears are gone.I'm tired of what I've been. Lord, make me over again.ChorusBut this time Lord change me let the work begin just now,this time Lord change me please change me some how,this time Lord change me let my life be rearranged,For I'm so tired of being stirred but not being changed/
