Without the Vine the branch can do nothing.
To the Vine it owes its right of place in the Vineyard, its life and its fruitfulness.
And so the the Lord Says, Without Me you can do nothing.
The Believer can each day be Pleasing to God ONLY in that which he does through the Power of Christ Dwelling in Him.
The Daily In-flowing of the Life-Sap of the Holy Spirit is his ONLY power to Bring Forth Fruit.
He Lives ALONE in Him and is for each moment Dependent on Him ALONE.
