What does the Bible say about the permanence of God's actions?

Ecclesiastes 3:14 states, 'I know that whatsoever God doeth, it shall be forever,' indicating that His works stand firm for eternity. This assurance is vital for believers, reminding them that God's promises do not falter or change unlike human promises. Additionally, Hebrews 13:8 affirms that 'Jesus Christ is the same yesterday, and today, and forever,' emphasizing the unchanging nature of God. Therefore, Christians can rest in the certainty that God's grace, love, and salvation are everlasting, providing a foundation of hope and stability in their lives.
