What does it mean to be spiritually alive in Christ?

Spiritual life in Christ signifies an ongoing relationship with Him, stemming from faith that connects the believer to the source of life. This is exemplified in John 11:25-26, where Jesus emphasizes that belief in Him ensures eternal life. Moreover, Paul highlights that faith connects believers to Christ's resurrection power, granting them a new identity and purpose. As such, spiritual life is characterized not just by existence, but by a vibrant communion with Christ, reflecting His glory and leading to fruitful living in service of Him.
