Schreiner believes works are necessary for salvation

 . . . "I will show later in this book, that demonstrate that good works are necessary for salvation." - Thomas Schreiner, Faith Alone, Page 87

Or again on Page 93 when discussing Wesley, without any qualifications or push back, he says, "in conclusion, Wesley tried to maintain the balance of Scriptures. He affirmed that salvation is by faith alone and that our righteousness is grounded in Jesus Christ. Still, good works are necessary as fruit for our salvation, and if they aren't present, we have no hope for eternal life."

If good works are necessary for salvation Mr. Schreiner then guess what? You have no salvation nor do you have assurance. Salvation is either all of Christ and what He did for the elect alone or it is of works. Hope is founded in Christ alone not in our works.
