What kind of work truly lasts before God? Many labour, build, preach, and organise—but how much of it will remain when tested by eternity? This book is born out of a deep conviction lived and proven over years: God only works in answer to prayer. Professor Zacharias Tanee Fomum believed that just as every project on earth demands a measurable cost, every work in God’s kingdom requires a definite measure of prayer. You do not stumble into lasting spiritual results. You pray—persistently, deliberately—until heaven responds. Anything produced outside this process may appear successful, but it is temporary. It is human effort. It fades. In this first volume in a series of 400 books on Answers to Prayer, you are invited into a documented life of prayer—500 clear, specific requests laid before God, followed by undeniable answers. From personal needs to global impact, from daily concerns to missionary breakthroughs, this book reveals a pattern: prayer offered, God responding, and results that endure. This is not theory. It is a record. It will challenge how you pray. It will expose what sustains true spiritual work. It will call you to build only what God Himself brings to pass. If you desire results that last—results born in God and sustained by Him—this book will show you the way.
