This book is a rich collection of inspirational expository sermons that emerged during a pivotal moment in my life during my four years of ministry in the Philippines. The sermons gathered in "13 Windows: Messages from Heaven" are designed for Christian readers, church members, and those interested in spiritual memoirs and sermons. They are powerful windows through which I have witnessed God's presence and grace in my life and in the lives of those I serve. Like vibrant yellow stained-glass panes, each sermon refracts light uniquely, illuminating key aspects of Scripture, personal experience, and hope.

Each sermon captures the dynamic interplay between human frailty and divine grace. They transcend mere theoretical discussions; they are living testimonies born from deep prayer, strong community, and the unwavering faith of Filipino worshippers. This collection embodies a proud tradition of spiritual memoirs and homiletic writings that have long inspired and testified to the faith of all who have attended our services. Readers seeking practical spiritual insights will find guidance and encouragement woven throughout these messages. As an added amenity, the author set aside a special place for notes at the end of each chapter, encouraging personal reflection and deeper engagement with the messages.
