How do we know that Christ is the root of grace?

Christ, referred to as the Root, is essential to the spiritual vitality of the Church and all its members. John 15:5 illustrates this beautifully, stating, 'Without me, you can do nothing,' emphasizing the believer's dependence on Him for spiritual nourishment. The sap that flows from the root symbolizes the grace and life that Jesus provides, underscoring His role as the source of all spiritual blessings. This dynamic relationship reveals how integral Christ is to the faith and sustenance of believers.
