How perfectly the Son does His work in John's gospel. He takes up one sinner after another from chapter 1 Through 10, and does not leave them for the hand of any other. He Himself perfects one and all giving them the sense of this, that upon leaving His physical person they had already found all of their needs as sinners fully met. No ordinance, no apostle, no church was needed to improve their state.
He takes up each of His saints in chapter 13, and washes them "clean every whit." fully ready, like accepted guests, to enter the house in a way worthy of it.
He takes up the house itself in chapter 14, prepares it for them—does this service all Himself—and then He takes up His saints all together, returning and receiving them unto Himself, to the house thus prepared for them.
There is a completeness and a singleness in all these operations. He does each service Himself alone, and does it perfecto, like the Son of God.
