“Abide in me” (John 15:4).
Jesus tells us to “abide” in Him because we already have been grafted onto Him. This spiritual engrafting, an accomplished fact, is made possible for everyone by His death on the Cross and it immediately became effective for each one of us at our Baptism.
By grace – power – we already are in Him and He insists further that we “abide” in Him and display increasingly fruitful lives.
