“Live in me. Make your home in me just as I do in you. In the same way that a branch can’t bear grapes by itself but only by being joined to the vine, you can’t bear fruit unless you are joined with me.” John 15:4
Why did Jesus use agricultural metaphors in today’s passage, and several others? The simple answer is because that was what His followers were familiar with. They were an agricultural society. They were all familiar with planting, harvest, and everything in between.
Today, not too many of us are farmers. Sure, we may plant a tomato or two in our backyard, but more often than not, our vegetables come from a supermarket, not dirt we worked with our own hands. No, if He were teaching this today He would probably use electronic gadgets to get His point across.
It might make it easier to understand His point if He talked about electricity, outlets, and power buttons. We would realize a little more easily that in order to have the power to live a victorious life, we must, must stay connected to Him. Yes, my laptop and smartphone will last for a little while off the charger, but in order to keep being productive, I have to get it hooked up to some external source of power.
Those vines He referenced were the source by which the plants received water and nutrients from the soil. They could live for a short while without being connected, but after a while they would be dead and unproductive – just like my computer.
If we want to live a power-filled, victorious life, we must stay plugged in to Him. Otherwise, we’ll just be biding our time until we become useless to Him or to ourselves.
