K.P. Yohannan emphasizes the importance of living by faith rather than relying on human logic and understanding. He shares the transformative experience of his brother, who believed in God's promise for his family's salvation, leading to their collective faith journey. Yohannan highlights that true faith operates in the supernatural realm, often defying our senses and logic, and encourages believers to trust in God's promises despite doubts and challenges. He warns against the enemy's tactics to discourage faith and urges Christians to resist these attacks, reminding them that all things are possible through belief. Ultimately, he calls for a return to a faith that acts on God's word, which is the normal way of life for believers.
