What does it mean that God's purpose cannot be stopped?

God's purpose cannot be stopped, which is a pivotal aspect of His sovereignty. As seen in Ephesians 1:11, all things are worked out in accordance with His purpose. This teaches us that no force in heaven or on earth can prevent God from fulfilling His preordained plans. This reality should encourage believers to remain steadfast in their faith, knowing that God’s providence oversees their lives and that His purposes, including the salvation of His elect, are assured and unchangeable regardless of worldly conditions.
