BUT... arent good works necessary for assurance?
God says
By grace you have been saved through faith, and that not of yourselves, it is the gift of God, not of works, lest anyone should boast.
Letter of Paul to the Ephesians
Chapter 2, Verses 8-9
That means
Knowing you have eternal life is dependent on believing Christs promise, not on the works you do. Since the possession of eternal life is based on believing Gods promise and on nothing else, how could works ever be necessary for assurance?
As weve already noted, many people think they gain eternal life by believing in Christ and by doing good works. Yet the Bible says that salvation is "the gift of God" and that it is "not of works, lest anyone should boast." Only by believing in Christ can you be sure you have eternal life.
Until you come to the place where you stop depending on your own good works, you wont have eternal life. To be saved you must believe in Christ, not in your works. And, once you believe in Christ, you will be sure you are saved because your salvation is dependent on your belief in Gods promise, not on your works.
