K.P. Yohannan emphasizes the necessity of relying on God's grace to overcome daily temptations and lead a holy life. He illustrates that just as batteries lose power over time, individuals who depend solely on their strength will ultimately fail. The sermon highlights the importance of complete surrender to the Holy Spirit, who empowers believers to live victoriously. Yohannan encourages seeking God's will in all aspects of life, big and small, rather than making decisions independently and then asking for blessings. This message serves as a reminder that true success comes from humility and dependence on God's grace.
