Would you be kind enough to tell me whether I am right with my interpretation of the expression in bold in the following excerpt from an article?
There are others whose relationship with God is largely based on feelings. Because feelings are transient—they come and they go, they change—these people's lives are constantly up and down and highly irregular. They blow hot and cold. John stresses that a Christian must follow the same pattern of life as Jesus lived, and He did not fly from pillar to post based on his emotions!
from pillar to post= from one thing or situation to another, hither and thither
The meaning of the expression in question is thought to allude to the banging about of a ball in the game of court tennis.
Thank you for your efforts.
