Theology is the subject of eternal blessing. The Church of the Living God is supposed to be the "pillar and foundation of truth" (1 Timothy 3:15). The first task of Christians is not to pursue innovation and practicality, but to be loyal to the revelation God has given us. This book explores God's self-revelation in the Bible, including how we know God, how to know ourselves, and how to live a rich life. I hope that everyone who walks on this path of faith can get help and guidance from this little book.
