How do we know that God's Word is unchanging?

Psalm 119:89 reassures us, 'Forever, O Lord, thy word is settled in heaven.' This verse underscores the eternal nature of God's Word, which remains unaltered by time or human opinion. Unlike earthly philosophies and teachings that may shift with societal changes, God's truth is constant and reliable. The believer can have confidence that what God has spoken will never fail or change, providing a firm foundation for faith and practice. This stability is crucial for Christians, as it undergirds their hope in the promise of salvation and the assurance of God's unwavering faithfulness throughout all generations.
