“When the brothers and sisters are joined together and knit together, there are no individualistic actions in the church, and there is not even a sense that we are individuals. There is only a sense of oneness based on the saints being joined together and knit together. This is an issue of the church being built up. In order to partake of the service that builds up the church, we cannot act individualistically or be separated from the saints. If we are separated, our work will tear down rather than build up the church.
A genuine and proper work joins and knits the saints together. An isolated and solitary work creates problems because there can be no building up without joining. There can be no building up without joining and knitting; there can only be tearing down.
In our history in the church life, we have clearly seen a few saints who seem to love the Lord very much and who seem to be very spiritual. However, such ones often become separated from the church and isolated from the saints. In a way they seem quite spiritual, but they are problematic because their spirituality lacks the element of joining and knitting. The more spiritual they become, the more they are separated from the church and the saints. In such a condition, these saints cannot be joined with the other brothers and sisters; they are like oil in water.
When a drop of water falls into a bucket of water, it immediately blends with the water and becomes indistinguishable from the other water. However, when a drop of oil falls into the bucket, the drop of oil remains on the surface, apart from the water. No matter how much the water is stirred, the drop of oil remains unblended. The drop may break apart into many drops, but it remains “alone” and “isolated” in the water; it is never blended with the water. Some saints are always isolated from the brothers and sisters, they are never blended with others, and they are always separate and solitary. This is quite dangerous.”
