Boundaries are important and set up for a purpose!
There are many boundaries in the game of
baseball, for example: foul lines, base lines, coaches boxes, and the strike zone!
The strike zone is a boundary of where a ball needs to be pitched in order for you to have the highest rate of success. Without that boundary we would not know the good pitches from the bad pitches.
The Bible also has boundaries set up so that we can be successful.
