Root
"Herein is my Father glorified, that ye bear much fruit; so shall ye be my disciples." (John 15:8)
The term "infructescence" comes to us from Botany and it refers to a state in which a fruit-bearing tree or plant, is able to bear fruit. It's the stage following "inflorescence" (the flowering), which in turn follows the "frondescence" (just leaves...). It means that the plant is ready.
"Say not ye, There are yet four months, and then cometh harvest? behold, I say unto you, Lift up your eyes, and look on the fields; for they are white already to harvest." (John 4:36)
God has called us to bear fruit for Him. As Jesus has introduced that analogy for us, we'd do well to consider just what it means for our life. In the above verse, Jesus is talking to His disciples who were flabbergasted that He'd even deign speak to a woman. But He knew. He talked to her, validated her and dealt with her sin then sent her on her way, full to overflowing. She went back and won over the entire town from where she'd come. She came to the well to fill her waterpot and left with a full heart. One touch from Him will fill you up and in turn create a harvest.
Shoot
"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." (John 15:4-5)
Jesus must be referring to the prophecy in Isaiah 11. The first verse speaks of a "Branch growing out of [Jesse's] (David's father) roots." It really doesn't matter what variety of fruit you are called to bear, everything we do when we abide in Jesus out of love and worship is fruit that glorifies God. But it's the abiding that causes it to happen. He'll see to it.
Fruit
So what is the "fruit" to which He's referring? Consider this:
"And the fruit of righteousness is sown in peace of them that make peace." (James 3:18)
For instance, when we endeavor to live "peacably with all men" (Romans 12:18), God's fruit can grow and be harvested. This is one of the ways that God "advertises" in this world. Your peace—that which you work hard for through the trial and toil of your life to procure—will be felt and enjoyed by those around you. And when they ask (they probably already know) where it comes from, declare.
Herein is the Father glorified. Because His peace is altogether different than the "garden-variety" offered by the world and its denizens.
It's Summer. The skies are blue and the weather's warm and clear. The Greek word for 'harvest', by the way, is 'therismos'. We get the prefix 'thermo-' from the same, referring to 'warm'. In other words, it's high time that the body of Christ bore fruit for Him. I'm not saying it isn't happening the world over, but look at the confidence expressed by the Lord: "Lift up your eyes and look on the fields (!)..." When's the last time you heard of one person leading their entire town to the Lord? Come to think of it, John chapter four. It'd be so cool to see this happen today!
There's one fruit I don't get though. It's called breadfruit and it's from a tree in the mulberry family. Apparently it tastes like bread, also potatoes. Very starchy. Whatever. To each their own. As long as your bearing fruit, no matter the variety.
Salut!
