No other one can do your work for Christ, or render your account at the judgment-seat.
In the realm of experience also the same is true.

Each person suffers alone, as if there were no other being in the universe.

Friends may stand by us in our hours of pain or sorrow, and may sympathize with us or administer comfort or alleviation, but they enter not really into the experiences.

In these we are alone.

No one can meet your temptations for you, or fight your battles, or endure your trials.
