“It is not good for man to be alone. I will make him a helper comparable to him.” — Genesis 2:18.
The spirit needs and craves righteous (holy/sinless) and loving fellowship with other spirits:
That’s why the Father has the Son and the Holy Spirit.
That’s why God created the angels and animals – other spirits to fellowship with.
And other kinds of spirits are great to fellowship with, but man needs his own kind of spirit to fellowship with, and that’s why God created Eve for Adam.
That’s why God designed and instituted family, to always have a special group of people amongst the billions of others to fellowship with.
That’s why God comes to literally live inside a believer 24/7/365 – to fellowship constantly, forever.
In this fallen world, some of us lack a family. Some of us lack a partner. But in the restored world, all of this will be perfected again.
In this fallen world, especially in these days, there’s a shortage of true “righteous” and “loving” fellowship (and more negative fellowship than positive), so it’s easy to become a recluse to protect yourself from hurt. But the spirit naturally knows how to handle these situations: with grace (undeserved kindness), patience, longsuffering, forbearance (tolerance), gentleness, goodness and humility, not returning hate for hate, but rather returning kindness for hate. The spirit naturally and genuinely cares for all spirits and their well-being, and is naturally compassionate. And other hurting spirits pick up on that and are greatly blessed with peace and joy from a spirit that genuinely cares about them.
And you are spirit. It is natural for you as your inner man, whether you believe it or not. So walk in the spirit – not in the flesh. Suppress the selfishness of the flesh and you will be free to operate in the spirit and you will be amazed and joyed at the goodness that comes out of you.
