I grew up with a semi-Calvinistic understanding of salvation. I knew that people were dead in sins and that dead people don’t do anything. But I did not understand much of how salvation actually worked.
When I first heard someone teach on the effectual call (also poorly described as irresistible grace) I balked at it. It didn’t seem to match up with my conception of salvation and my experience of life. When the gospel was preached, it seemed that the Spirit was working generally in people’s hearts, and they either responded to that work or rejected it. But that was all that was happening.
While in graduate school, I took a class on Romans. When studying through Romans 8—specifically verses 28–30—I became convinced that the effectual call was a biblical teaching. Read more about How I Became Convinced of the Effectual Call
