In part 2 of the "Living with Yourself" video series, Andy Stanley stresses the importance of monitoring one's heart to ensure alignment between one's inner self and outer behavior. He emphasizes that man-made rules are not enough to live a life of integrity and that one must focus on the inner condition of their heart to align themselves with God's will. Stanley also discusses the dangers of ignoring what is going on inside oneself and the importance of tending to one's soul to prevent toxic emotions such as guilt, anger, greed, and jealousy from defiling it. Lastly, he addresses the issues of resentment, greed, and jealousy, suggesting that forgiveness, celebrating others' success, and giving generously are the solutions to these problems.
