Why is the concept of measuring the church significant?

In the context of Zechariah 2, the measuring line represents the exactness with which God has planned and orchestrated the church's existence. Just as Jerusalem was measured for its dimensions, the church is built according to God's design laid out before the foundation of the world. Every member has been predetermined to be a part of this spiritual edifice, underscoring the doctrine of election and the assurance that no one added to the church is by chance. This is crucial for understanding that the church is not merely a human institution but a divine assembly with purpose and direction.
