But what about that

big yellow bull dozer?

What was it supposed to mean?

A short while later while I was being a witness, The Truth came to me, and then I felt so stupid.    Why I hadn't been able to see The Truth was beyond me. The bull dozer is used to move that which will not move, or that we can not move.  It is used for the seemingly impossible tasks. The bull dozer as well was being used to represent The Same Divine Intervention necessary in the Salvation of man.

JESUS IS THE WAY, THE TRUTH, THE LIFE; JESUS IS THE ONLY WAY, JESUS IS THE ONLY WORKER, AND IF IT IS NOT BY GRACE, IT IS BY WORKS!
