Abide in me, and I in you. As the branch cannot bear fruit of itself, except it abide in the vine; no more can ye, except ye abide in me.
Ver. 4. As the branch cannot bear fruit, &c.] All our sap and safety is from Christ. The bud of a good desire, the blossom of a good resolution, and the fruit of a good action, all come from him, Gratia praevenit nos ut velimus, et subsequitur ne frustra velimus. (Augustine.)
