Once saved, how does one remain saved?

God has put His laws in our hearts and written them on our minds; thus, our conscience testifies of our conduct in this world. The Lord invites everyone to come and receive forgiveness of sins and the gift of eternal life. Many people yearn for this liberation from sin and condemnation but struggle with the question of how to obtain it. Can one be saved and remain saved to the end with a clear conscience before an all-seeing God? This book shows in a simple way how anyone can have this assurance-for He who promised is faithful.

Matthew 11:28, "Come to me, all you who are weary and burdened, and I will give you rest."
