This book is a must read. It covers the need of repentance along
with faith for salvation (Acts 20:21). They are like two sides of a
coin. One side is for "faith in our Lord Jesus Christ" while the
other is for "repentance toward God." To have saving faith, one
must first acknowledge that he is ungodly. This is in
contradiction to today's "easy believism." I do not read a lot of
books, but this one helped me and encouraged me A LOT!
