Gospel Guidebook: Getting and Keeping It Right 
한국어 日本語
Introduction
If you have not yet believed in Jesus Christ for eternal life, I would recommend reading the tract The Secret to Life's Meaning and watching the video The Gospel - Plain and Simple. If you are a believer, I would recommend my short book Jesus Christ the Savior of the World, as well as the short booklet Starting My New Life in Christ.
It is vitally important to understand that eternal life is a gift from God received through belief in Jesus Christ. This means that it cannot be appropriated through repentance of sins or any other works. This also means that it is not dependent on a transformed life of good fruit. It is truly a gift with no strings attached (see John 4:10, Romans 6:23, Ephesians 2:8-9). This page contains articles and short books written by me on the topic of Free Grace and related topics. At the bottom of the page, I also include some links to books, articles, and videos I have found useful.

Tough Texts: Did Jesus Teach Salvation by Works? by Zane Hodges and Robert N. Wilkin (This book does a pretty good job with the Sermon on the Mount, but I did find some of the explanation to be incomplete. I may try to do a review of this book someday and supplement it with my own explanations.)
