This document discusses the security of salvation. It explains that salvation requires repentance from sin and faith in Jesus Christ, who lived a perfect life, died for our sins, and rose again. Having faith means inviting Jesus to govern our lives. Our security depends on God, not our feelings, which can change. We must trust that God is able through Christ to keep us saved until eternity based on His promises and faithfulness. The document reassures the reader that if they have repented and believed, their salvation is secure in God.
