I am the true vine, and my Father is the husbandman. Every branch in me that beareth not fruit he taketh away: and every branch that beareth fruit, he purgeth it, that it may bring forth more fruit. Now ye are clean through the word which I have spoken unto you. 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. I am the vine, ye are the branches: He that abideth in me, and I in him, the same bringeth forth much fruit: for without me ye can do nothing. If a man abide not in me, he is cast forth as a branch, and is withered; and men gather them, and cast them into the fire, and they are burned. If ye abide in me, and my words abide in you, ye shall ask what ye will, and it shall be done unto you.
John 15:1-7 (KJV)
Here we can see that both fruitful and unfruitful branches are all on the Vine. So it is possible to be on the vine and still be fruitless. From verse seven I am convinced that one of the main fruits the branch can bear is the fruit of prayer. A believer that is truly abiding and living in union with the Lord and His Word will produce abundant fruits of answered prayers.
Yours in Christ, pastor Festus Nsoha.
