In this sermon, the preacher emphasizes the importance of making room for God's blessings in our lives. He uses the story of a widow in debt to illustrate this point. The widow, whose husband was a student of the word of God, finds herself in a desperate situation with creditors threatening to take her two sons as bondmen. However, when she seeks help from the prophet Elisha, he asks her what she has in her house. She initially feels she has nothing, but eventually realizes she has a pot of oil. This parallels the New Testament story of Jesus feeding the multitude with just a few loaves and fishes. The preacher encourages the audience to not downplay what they have and to stop making excuses for not serving God.

A.B. Simpson emphasizes the significance of recognizing the Holy Spirit's sufficiency in our lives through the story of the widow and her pot of oil. He illustrates that while the widow felt she had nothing, the pot of oil represented the Holy Spirit, which is more than enough for all our needs if we learn to utilize it properly. The sermon teaches that our capacity to receive the Holy Spirit expands through the challenges we face, as God uses our trials to create opportunities for greater fullness of His grace. Simpson encourages believers to view their difficulties as vessels for receiving more of God's presence and power.

Zac Poonen preaches on God's call to Moses, emphasizing how God starts with what is already in our hands, just like He did with Moses' staff and Elisha's jar of oil. Through the signs given to Moses, Zac highlights the closeness of Satan and the need for believers to have authority over the enemy without fear. He stresses the importance of recognizing the corruption within our flesh and the need to be crucified to the world, pouring out worldly desires and worship to death.

Watchman Nee emphasizes that God desires us to be continuously empty in order to be filled with the Holy Spirit. He illustrates this through the story of a woman who had only a pot of oil, highlighting that the more we empty ourselves, the more room we create for God's fullness. The sermon teaches that our responsibility is to keep emptying ourselves, while God's role is to fill us with His Spirit. Nee reminds us that God waits for us to recognize our need for Him, and only those who acknowledge their emptiness will be filled. Ultimately, the message is about the importance of maintaining an open heart to receive God's abundant blessings.
