What a trellis is to a vine, a rule of life is to abiding. It’s a structure—in this case, a schedule and a set of practices—to set up abiding as the central pursuit of your life. It’s a way to organize all of your life around the practice of the presence of God, to work and rest and play and eat and drink and hang out with your friends and run errands and catch up on the news, all out of a place of deep, loving enjoyment of the Father’s company. If a vine doesn’t have a trellis, it will die. And if your life with Jesus doesn’t have some kind of structure to facilitate health and growth, it will wither away. Following Jesus has to make it onto your schedule and into your practices or it will simply never happen. Apprenticeship to Jesus will remain an idea, not a reality in your life.
