To abide in Christ is to dwell where life itself flows, to remain in the living Vine until His life becomes the pulse of our own souls. Our Lord says, “Abide in me, and I in you… as the branch cannot bear fruit by itself unless it abides in the vine” (John 15:4–5), and here is the heart of the Christian life: not striving alone, not moral effort by itself, but a living union with Christ in which grace flows as sap through the branch. What have the great teachers of Christianity told us about this vital relationship? The earliest shepherds of the Church proclaimed this mystery with urgency and joy. Think, for example, of Ignatius of Antioch (c. 35–107 AD), who, as he walked toward martyrdom in the first century, exhorted believers to remain in Christ Jesus through faith, unity, and the Breaking of Bread.
