Pastor's main point was taken from 2 Kings 4:3 and 6. For reference, here's the text:
2Ki 4:1 Now there cried a certain woman of the wives of the sons of the prophets unto Elisha, saying, Thy servant my husband is dead; and thou knowest that thy servant did fear the LORD: and the creditor is come to take unto him my two sons to be bondmen.
2Ki 4:2 And Elisha said unto her, What shall I do for thee? tell me, what hast thou in the house? And she said, Thine handmaid hath not any thing in the house, save a pot of oil.
2Ki 4:3 Then he said, Go, borrow thee vessels abroad of all thy neighbours, even empty vessels; borrow not a few.
2Ki 4:4 And when thou art come in, thou shalt shut the door upon thee and upon thy sons, and shalt pour out into all those vessels, and thou shalt set aside that which is full.
2Ki 4:5 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.
2Ki 4:6 And it came to pass, when the vessels were full, that she said unto her son, Bring me yet a vessel. And he said unto her, There is not a vessel more. And the oil stayed.
So he was describing the situation, the boys bringing in all the pots for the oil, and there were pots everywhere; she was "going potty." And the idea is (based on the main sermon text of Isa 54:2 Enlarge the place of thy tent, and let them stretch forth the curtains of thine habitations: spare not, lengthen thy cords, and strengthen thy stakes;
Isa 54:3 For thou shalt break forth on the right hand and on the left; and thy seed shall inherit the Gentiles, and make the desolate cities to be inhabited.) that we need to go pot-y and make room for the breakthrough. And not only make our home, our vision, our territory larger, but to strengthen the stakes (tent pegs) - to make the house stronger. (We need to build according to God's plan, not just any old way.)
So that's what I got from the sermon.
