Many Christians suffer because they don't fully understand who God is. People who are not Christians understand Him even less. If we knew what God expects of us and what He wants us to know and understand, then we would experience His blessings instead of suffering as we sometimes do.
The author has been a dedicated Christian for 30 years. This book offers basic truths about God that he believes are needed by every Christian (and non-Christian) who wants to reduce the amount of suffering in their lives. The book begins with the most fundamental truths, then builds on those truths to assist readers in increasing their understanding. The truth of the Gospel has not changed in 2000 years. However, our understanding of the Gospel has grown, as each generation of Christians understands more than the previous generation.
The author believes this book contains the next steps in increasing our knowledge, as we draw deeper wisdom from the scriptures to reduce our suffering. God offers us eternal life in a heaven filled with His mercy and goodness, and He offers us the same here on earth. There is no future other than the future that God offers us, through the sacrifice of His Son Jesus Christ on the Cross. Jesus died on the Cross, so we can live our lives full of grace and peace. We should also experience many of God's miracles as we live out our lives here on earth. This will happen if we choose to listen to His Word and believe and follow His Word. God looks closely at the quality of our decision making, since our decision making will determine the contentment of our lives. The author has entered God's rest and so can you.
