This document outlines a lesson on assurance of salvation. It discusses how lack of assurance prevents spiritual growth and explores the biblical plan of salvation according to Ephesians 2:8-10. The plan of salvation has three key points: 1) We are not saved by works but 2) by grace through faith, and 3) we are saved for good works. Understanding this plan provides assurance of salvation and allows Christians to grow in their relationship with God.
