How do we know that our spiritual life is in Christ?

Believers find their spiritual life in Christ as He embodies the essence of life for Christians. Our connection to Christ is vital; as Paul proclaims, 'When Christ, who is our life, shall appear, then shall we also appear with him in glory' (Colossians 3:4). The relationship we have with Him is not based on our merit or effort but is sustained by His divine grace. This union with Christ means that our lives are intertwined with His, relying on Him for strength, righteousness, and the ability to bear fruit. Therefore, when Christians seek comfort in their faith, they rely upon this foundational truth that their spiritual essence hinges upon their relationship with Christ.
