How do we know Christ's faithfulness is true?

Christ’s faithfulness is demonstrated throughout scripture, reflecting His nature and commitment to His people. In Colossians 1:2, believers are referred to as 'faithful brethren in Christ,' highlighting that their faithfulness is rooted in Christ's faithfulness to them. Since God does not waver in His promises, we can trust that Christ’s work of salvation is secure. Additionally, in Romans 8:38-39, we see that nothing can separate us from the love of God in Christ Jesus, affirming His steadfastness and reliability. This assurance allows believers to walk in faith, knowing that His faithfulness remains regardless of circumstances.
