Stonewalling within a couple refers to the act of shutting down or becoming unresponsive, often as a defense mechanism during conflicts. Though the Bible does not directly address stonewalling, it emphasizes the importance of open communication, patience, and understanding within relationships. In Ephesians 4:26-27, it urges against letting anger persist, encouraging resolution and finding common ground. Therefore, stonewalling can hinder the biblical principles of healthy and loving interactions, as it impedes the couple's ability to foster understanding and work towards reconciliation.
