I’m paraphrasing, but I liked this anecdote by pastor Lutzer:
A man was walking through a forest carrying his cross. The cross was so heavy and he just couldn’t take it. When he met a woodsman along his path, he asked the man to chop off just a bit of his cross. “It’s just so heavy and I have to travel far,” the man explained.
The woodsman was happy to help and chopped off a big bit.
This made all the difference in the world and the man was able to move along much more easily.
Eventually, the path led to a chasm. It was impossible jump or walk across the chasm. The man had to use his cross as a plank and walk over it. Yet when he laid his cross down he soon figured out it was too short, too short my exactly the length that was cut off.
