I am the vine, ye are the branches; that is, I am as the vine, you are as the branches: without the continual influence of the vine upon the branches, they bring forth no fruit; but that influence continuing, no plant is more fruitful than a vine is: so without the continual influence of my Spirit of grace upon you, you will be altogether barren and unfruitful; but if you have that influence, you will not be fruitful only, but very fruitful: for without my continuing such influence, you will not only be able to do little, but you will be able to do nothing that is truly and spiritually good and acceptable in the sight of God.
