why God allows useless efforts:

when we believe in god and depend on Him for guidence, still we go on doing futile efforts for achieving some thing. suppose we want to apply for a job which god accepts and blesses for us.. we pray Him to show us a good job which he decides for us. But, then we have to apply lots of jobs where we are rejected.. finally we get one job.. then, if we think why God allowed us to apply all those useless .
jobs, dream about them as if God is going to give us those as gift.. If he loves to curtail useless work, when some thing is decided, he can stop us when we request Him to allow us to go to the interview, if only if he likes it.. Even when we depend on God , we have to do lot of futile efforts. When we sow seeds, we have to sow dead and useless seeds also, he is not separating them from good seeds for us.. i think he loves our effort and experience.
