Jesus said to Peter, “Feed My sheep,” but He gave him nothing with which to feed them (John 21:17). The process of being made broken bread and poured-out wine means that you have to be the nourishment for other people’s souls until they learn to feed on God. They must drain you completely— to the very last drop. But be careful to replenish your supply, or you will quickly be utterly exhausted. Until others learn to draw on the life of the Lord Jesus directly, they will have to draw on His life through you. You must literally be their source of supply, until they learn to take their nourishment from God…
Oswald Chambers – Are you exhausted Spiritually?
I think of it in terms of babies. My wife and I have joked that our kids are sucking the energy out of us. And to a certain extent it’s true. Infants are completely unable to care for themselves and even as they get older while they can do more on their own, they still require lots of attention and energy. Don’t get me wrong, I’m not complaining. I’m trying to draw a comparison.
If we’re not mature Christians, then we are effectively draining Christians and as odd is may sound we need to grow to become the drained. Thats the only way to reproduce.
