Why is it important for faith to stand in the power of God?

The Apostle Paul emphasizes that faith should not rest in human reasoning or the persuasive words of men. He argued that if one's faith is based merely on human argumentation, it is precarious and easily influenced. The true strength of faith comes from the power of God, which is unchanging and steadfast. Those who hear the Gospel and respond in faith must do so with an understanding of its divine authority and transformative power. The narrative of the Samaritan woman illustrates this point - her testimony led others to seek Christ, but true belief came when they heard Him for themselves. Therefore, the assurance of salvation is found in a personal relationship with Jesus Christ, which is enabled solely through the work of the Holy Spirit.
