Charles Finney emphasizes the necessity and duty of being filled with the Holy Spirit, arguing that Christians often misunderstand their obligation to seek the Spirit's influence. He warns against the dangers of complacency and hypocrisy, asserting that the lack of the Spirit leads to spiritual stagnation and guilt. Finney outlines the reasons many fail to be filled with the Spirit, including insincerity, worldliness, and neglect of known duties. He stresses that being filled with the Spirit is essential for spiritual growth, effective prayer, and fulfilling one's moral obligations. Ultimately, he calls for a sincere pursuit of the Spirit to experience true spiritual vitality and effectiveness in ministry.

Peter Brandon emphasizes the necessity of being filled with the Holy Spirit, using the story of a widow from 2 Kings 4 to illustrate how God provides in times of desperation. The widow, facing the loss of her husband and the threat of losing her sons to creditors, turns to the prophet Elisha, who instructs her to gather empty vessels and pour out her small amount of oil. This act symbolizes the filling of the Spirit, where God can multiply what little we have when we surrender to Him. Brandon highlights the importance of prayer, humility, and recognizing our own emptiness to receive God's fullness, ultimately leading to restoration and blessing.
