How do we know God's love never fails?

The assurance of God's eternal love is critical to the believer's faith, illustrated in 1 Corinthians 13:8, which declares, 'Love never fails.' This love is manifested in God's sacrificial work through Christ, as seen in 1 John 4:10, where it states, 'In this is love, not that we loved God, but that he loved us and sent his Son to be the propitiation for our sins.' This unwavering love secures the believer's salvation and emphasizes that nothing can separate us from it, as expressed in Romans 8:38-39. Such profound assurance empowers believers to rejoice, knowing that God's love will always sustain them, regardless of life's trials.
