God's purposes cannot be altered because He is sovereign and works everything after the counsel of His own will.
The assurance that God's purposes cannot be altered comes from the understanding of His sovereignty, as emphasized in Ephesians 1:11, which states He works all things according to the counsel of His will. God's determinative counsel is evident throughout Scripture, where human actions, both good and evil, ultimately serve His divine purposes. The actions of Joseph's brothers, for example, were meant to be evil, yet God used their intentions to fulfill His greater plan (Genesis 50:20). This illustrates that no matter what circumstances occur, God's purpose remains unchanging and will always come to fruition as He decrees. Furthermore, God uses both obedience and disobedience to achieve His will, which affirms the certainty of His unalterable plans.
