Hugh Binning, Works, p. 292:
If we were once enrolled in this blessed fellowship with the Father and the Son, then it follows, as a fruit and result of this, that we should have fellowship one with another. And truly the more unity with God, the more unity among ourselves: for he is the uniting, cementing principle, he is the centre of all Christians; and as lines, the farther they are from the centre, the farther distant they are from one another, so the distance and elongation of souls from God sets them at further distance amongst themselves. The nearer we come every one to Jesus Christ, the nearer we join in affection one to another; and this is imported in that of Christ’s prayer, “That they may be one in us,” John 17:21, 22. No unity but in that one Lord, and no perfect unity but in a perfect union with him. I would exhort to study this more, – to have fellowship one with another, as members of the same body, by sympathy, by mutual helping one another in spiritual and temporal things.
