When Christian relationships have as their basis any other expectation than the efficacy of the blood of Christ to reconcile us both to God and to one another, we will indeed be torn apart through vanity and evil suspicion.
An experienced one, supposing himself to be great in understanding, may begin to expect great spiritual understanding of another; and a less experienced one, thinking himself to be wise, may yet be quite carnal in some way, expecting his brethren to fawn at his every self-serving whim: and both will be gravely disappointed – the one forgetting that only according to Christ’s blood is he himself being made truly spiritual, and the other not yet seeing the true weight of his calling. Yet in the case of both, it is truly the same deficiency, and only a differing expression of the same carnality, which strays from the faith. In short, they have each neglected, for their own souls’ vain satisfaction, their ongoing participation in the blood of Christ, which alone leaves no man disappointed, and alone disarms the vanity of both, unto a true and grounded reconciliation.
If we are to ever truly help one another in our weaknesses, we might begin by acknowledging the weakness that we all share to some degree: which is a lack of faith in the imminent power of the blood of Christ to make straight our way unto His throne of grace. For of this, there cannot be too much; and by this repentance, much joy of His salvation can be restored in our midst.
Then we might perhaps begin the very first steps of walking as His Body, and eventually be worthy to speak of moving on to maturity.
It is to be hoped.
