How do we know that God is faithful in our fellowship?

We can trust in God's faithfulness in our fellowship because it is rooted in His character. As stated in 1 Corinthians 1:9, 'God is faithful, by whom you were called unto the fellowship of His Son, Jesus Christ our Lord.' This verse reassures believers that our relationship with Christ is not dependent on our fickle nature but on God’s unwavering commitment. God's faithfulness is demonstrated through His actions throughout scripture, fulfilling promises and calling His people into a relationship with Himself. This assurance allows Christians to find confidence and peace in the fellowship we share in Christ, knowing that it is grounded on His perfect reliability.
