What is the foundation of the Gospel? What is it that separates us from God? Why do we need a Saviour? The answer to all three of these questions is sin. Sin is not merely mistakes or decisions that we make, it is the lethal killer lurking in our veins. This book seeks to show a truth that has largely disappeared from many a pulpit in this modern age, the truth that we do owe God a debt, that we do stand in desperate need of a Saviour. But there is hope. This is the foundation of the Gospel, the hope for all.
