Are you saved forever or can you lose your salvation? This is a question that has become controversial for centuries. One does not need to rush to a conclusion without first knowing what the Holy Bible teaches about the salient doctrines like salvation, sin, redemption, reconciliation, repentance, regeneration, sanctification, justification, adoption, election, predestination, glorification, sealing, eternal security of believers and other related doctrines. These are what Pastor Bayo Afolaranmi systematically analyses in this book.
