When He Calls Your Name is a book written by a Vietnamese Christian. The book is about the importance of putting faith in Jesus Christ. That is the way to peace, liberation from fear. The book was written when the author prayed, sang hymns and was on the way to testify in Viet Nam. When reading this book, you will realize three things: Our knowledge and successes cannot create deep peace in our heart. Knowledge can change your mind but cannot heal your heart. Jesus Christ can heal your heart. The relationship with Jesus Christ helps you refresh your soul, refresh your mind. As apostle Peter once wrote: "Though you have not seen him, you love him; and even though you do not see him, you believe in him and are filled with an inexpressible and glorious joy.
