In his sermon "Incognito Righteousness," Pastor Jamie Self explores Matthew 6:1, emphasizing the importance of practicing righteousness discreetly, without seeking the approval or admiration of others. He outlines three key points: the warning to "beware," the nature of righteousness before others, and the concept of receiving no reward from God if our acts are done for human recognition. Self connects this teaching to the broader context of Jesus' Sermon on the Mount, highlighting how genuine righteousness rooted in love leads to God's kingdom rewards, contrasting with the shallow accolades of human praise.
