Faith is defined as having confidence and assurance in things hoped for but not seen, and involves worshipping God, being patient while waiting on Him, living a holy life, persevering through trials, and trusting God rather than relying on oneself. True faith results in works and obedience to God's word, not just words without action. Faith has Jesus Christ as its central object and is based on His finished work on the cross to overcome sin and give believers authority over Satan. The document provides guidance on growing one's faith through studying Scripture, prayer, taking every thought captive to Christ, and demonstrating faith through actions rather than relying on personal effort alone.
