How do we know God's purpose is unchanging?

The unchanging nature of God's purpose is a profound comfort for believers. Isaiah 46:10 declares, 'My counsel shall stand, and I will do all my pleasure.' This illustrates that God's plans are not subject to the whims of man or the forces of nature; they are guaranteed to come to fruition. What God has purposed from eternity will undoubtedly be realized in time, reflecting His sovereign will and intention. This is particularly significant in matters of salvation, as believers can trust that those whom God has chosen will ultimately be saved. Therefore, understanding God's immutable purpose helps reinforce our faith, knowing that our salvation is secure based on God's eternal decree, not on our mutable actions or decisions.
