This blog series will be the fuller versions of the lessons I give there, yet I do want to maintain the simplicity of the lessons, so I won't endeavor to expand them too much.  If you do happen to read, please pray for the students; high schoolers are in dire need of the gospel. This is the first full lesson of the year, in which I endeavor to explain a full understanding of hamartiology and total depravity (point one of five-point Calvinism) — in twenty minutes.  Difficult?  No.  Impossible.  But, the Lord is good, and by His grace, I think I helped more than I confused.
