"And when thou art come in, thou shalt shut the door upon thee and upon thy sons." You will notice that "sons" is used, indicating the dignity of the new position of those who are empty vessels ready to be filled with the holy Word of God by the Spirit of God. The doors are closed to the world and its defilements.
"And shalt pour out into all those vessels, and thou shalt set aside that which is full." There should be discernment in the assembly to recognize the service for which the Lord by the Spirit has fitted a vessel. When God raises up a person to go out to gather others in, there should be a desire on our part to help him. Sometimes we may allow the flesh to act in criticism, looking for mature spirituality rather than a heart for Christ.
"So she went from him, and shut the door upon her and upon her sons, who brought the vessels to her; and she poured out." 2 Kings 4:5.
The woman acts on the instructions which he had given her. This is faith. Her sons go out and bring in new vessels for her to fill.
In the assembly we learn truth. God does not repeat Himself, so new revelation is not given to each, but the filled vessel is poured out to fill the empty one. The assembly does not teach but is to be the pillar and support of the truth that is taught through the individual vessels.
Are you inside the closed door of the assembly, or are you saying, "I can learn the truth and worship God with anyone"? No, you must be willing to be filled with the vessels the Lord has provided and where the truth is collectively maintained by the assembly.
"But the hour cometh, and now is, when the true worshippers shall worship the Father in spirit and in truth: for the Father seeketh such to worship Him. God is a Spirit: and they that worship Him must wor ship Him in spirit and in truth." John 4:23,24.
God is a Spirit. The believer is indwelt by the Holy Spirit. The worship must be in truth. The truth is declared in the Scriptures, and unless the Scriptures are our guide, we are not worshipping God in Spirit or in truth.
God tells us that the place where He is must be holy. The assembly is His habitation on the earth by the Spirit. If there is allowance of doctrinal or moral evil, the assembly is defiled and the evil must be judged. That is what is meant by the closed door. There is room for every believer on earth. It is the assembly of God, but any who are connected with evil must be barred from fellowship at the Lord's table until the evil is judged.
