Can Salvation be earned or lost through sin?

Salvation is the unchanging thread that runs through every chapter of this book, by Dr Robert Moreton. Whether we are examining the misapplication of Scripture, the authority of Paul's gospel, the impossibility of earning righteousness, the reality that Christians still battle the flesh, or the fear-driven claim that sin can undo what God has done, the conclusion remains the same. Salvation is the work of God from start to finish. It is given freely, received by faith, secured by Christ, and sealed by the Holy Spirit. No human effort can achieve it, and no human failure can overturn it. The believer's confidence rests not in their own performance, but in the finished, perfect, and irreversible work of the Lord Jesus Christ.
