What does the Bible say about God's purpose in salvation?

According to Scripture, particularly Romans 8:28-30, God's purpose in salvation has been irrevocably established from eternity past. Ephesians 1:4-5 emphasizes that God chose His people before the foundation of the world, signifying that His plan for salvation is deeply rooted in His sovereign will. Despite the relentless opposition from Satan and the world, God's purposes will prevail. Revelation 12 illustrates Satan's attempts to hinder God's plan, yet ultimately, Christ triumphs over sin and death, securing salvation for His elect. This assurance gives believers hope that no matter the trials facing them, God's redemptive plan is unstoppable.
