While sermons can challenge and inspire a woman, genuine life-change happens when someone enters her emotional world, connects with her, and encourages her on a personal level. She experiences the most growth within relationships that provide empathy, presence, conversation, and emotional connection.
It would be unhealthy for a male pastor or leader to have the relationship described above with a woman in his congregation. The Bible tells us that women are the best models of godly behavior for other women (Titus 2). Women understand women. Allowing women to minister to other women will prevent unhealthy emotional attachments between male pastors and women in the congregation. This is why ministry to women, by women, is a vital part of a healthy congregation.
