This book is a concise Christian guide that explores the biblical connection between faith and obedience and explains the continuity between Old Testament faith and New Testament faith. It teaches that genuine faith is never separate from obedience, but expresses itself through a life that trusts and follows God, while also showing that believers in both testaments are saved by grace through faith, with the difference being the degree of revelation given through Christ. Blending Scripture, practical application, reflection questions, action steps, and journaling prompts, the book is designed to help readers grow in spiritual understanding, deeper trust in God, and a more obedient walk with Him.
