How can a person, independent from consistent fellowship with the body of Christ, the church, still be a part of it? A person thinking this way is sliding away from God's intention, as His Word clearly shows. He fully intends we be active members of a physical body as well as the spiritual organism. Is the church only a spiritual organism? If the spiritual organism is the only important aspect, why even have congregations? Could congregations play a major role in preparing us for God's Kingdom?
Let's look at this from another angle. God intends mankind to be an active and contributing part of a physical community. "And the LORD God said, 'It is not good that man should be alone; I will make him a helper comparable to him.' . . . Therefore a man shall leave his father and mother and be joined to his wife, and they shall become one flesh" (Genesis 2:18, 24).
Perhaps verse 18 could be rephrased as, "It is not good that man be independent." Our God establishes principles and patterns in His Word from which we can extract wisdom, the practical application of truth. Some of the most basic and fundamental patterns for His purpose are established very early in Genesis.
What is He showing here? That, in relation to God's purpose, the most and the best will not be produced in us if we are alone. If we are independent, we remove ourselves from the circumstances that will produce the most toward His purpose. In this specific context, God is not commanding everyone to marry, but He is clearly showing that marriage is generally better than remaining single.
Everyone understands from his own experiences that the more people who comprise a unit or community, the greater the number and intensity of problems. This occurs largely because our carnality drives us to compete rather than cooperate. Sometimes a person desires so strongly to be independent of this kind of community relationship that he separates himself in order to be completely free from the suspicions, distrust, offenses, and other hardships that occur within a group. To put it another way, it is similar to a soldier running away from the battlefield to protect himself.
In its rawest form, it is selfishness and self-interest. It can be self-serving avoidance of being useful, of contributing steadfast strength and encouragement, of being a right example to others, or of being found wrong and corrected. If nothing else, we are detaching ourselves from the unit to which God intends we show allegiance and service.
