How do we know that our spiritual union with Christ is real?

The reality of our spiritual union with Christ is evidenced through the transformative change that occurs in the life of a believer. According to John 15:5, Jesus is the vine, and those who abide in Him produce much fruit, which reflects the work of the Holy Spirit within us. This union isn't merely a declaration but a profound new birth that radically alters our desires, ambitions, and values, aligning them with Christ's. Additionally, the Holy Spirit, referred to as the Comforter, reinforces our identity in Christ by enabling us to bear witness of Him. As believers experience an ongoing relationship with Christ, they confirm their union through obedience, fruitfulness, and a growing desire for holiness.
