I have no one to put me into the pool - John 5:7
A good man always knows his limitations
An unnamed sick man met Jesus one day knew his limitations by reponding with an "I can't"
He was unable to walk for 38 years and he wait for someone to help get him into healing waters of the pool of Bethesda
What he obvioudly couldn't do, Jesus did
The man knew that on his own, he had no hope of changing his situation
I CAN'T is sometimes the words Jesus wants to hear
That phrase comes from the lips of the person who realizes his need for complete dependence of Christ
