When we are not straight with God we cannot be filled or fully filled and used by God in the overflow experience. Before you pour into the vessel you must shut the door behind you.
So she went from him and shut the door behind her and her sons; they were bringing the vessels to her and she poured. 6 When the vessels were full, she said to her son, "Bring me another vessel." And he said to her, "There is not one vessel more." And the oil stopped. (2 Kings 4:5)
There are many distractions from pouring the oil to the jars. The oil is available and needs to be poured to the other vessels. Only fill up to your desire and commitment. Shut the door behind you. But before you pour, you need to close the door and start pray so the oil can pour in to the empty vessels. Whatever is taking your concentration away from God, needs to be shut. Whatever hinders you from pouring the oil to the vessels need to be shut.
