This document calls believers to "Arise and Build" by strengthening their spiritual defenses. It references the broken-down walls of Jerusalem that left God's people vulnerable and in affliction. Believers are encouraged to pray and fast to seek God's help in repairing the breaches, which allow "little foxes" like idolatry, materialism, and habitual sins to spoil their spiritual lives. The goal is for believers to put on the full armor of God so they can withstand attacks and build up the walls of their faith.
