Shane Idleman addresses the common phrase 'Who are you to judge me?' in his sermon, emphasizing the importance of understanding biblical judgment in context. He highlights the issue of biblical illiteracy, where many Christians misinterpret scripture to justify their actions, particularly the 'judge not' verse. Idleman argues that while we are not to judge hypocritically, we are called to discern and speak truth into our culture, especially regarding moral issues. He encourages believers to examine their own hearts before critiquing others and to engage with scripture deeply to understand God's will. Ultimately, he reminds the congregation that true judgment should come from a place of humility and love, not arrogance.
