On the contrary, it was the perversion of the Gospel of salvation by grace through faith APART from works that Paul called out in his letter to the Galatians. You might want to include that in your Bible study. No one here has denied that God has prepared good works for us that we are enabled to do through his grace working within us, but nowhere in Scripture does it ever say grace AND works merit eternal life. The very meaning of grace is undeserved and unmerited favor so how can adding works to faith STILL keep us saved by grace. If we are saved by grace then it is not by works because grace would not be grace. If we are saved by works then it cannot be by grace because work would not be work. Read it for yourself Romans 11:6.
That is nonsense too; St. Paul taught salvation by Grace alone through both faith and good works (Eph. 2:5-10, Titus 3:5-8, Gal. 5:6), however not salvation by the works of the Jewish or any other law. How many times do I have to explain this simply truth to you?
If we are saved by grace then it is not by works
Grace indeed is not produced by our works.
