The document discusses ways to determine if someone is a true Christian or not. It summarizes Jonathan Edwards' view that true Christians can be identified by their holy affections and love for God over sinful things, as well as their hatred of sin. It also notes that Christians produce good works and spiritual fruit from having been born again by the Holy Spirit. However, determining salvation is difficult, as outward appearances can be deceiving, so the Bible teaches that people's salvation can only be known with certainty by God.
