In the journey towards a Christian marriage, it’s crucial to be attentive to red flags—warning signs that something may be problematic. These red flags serve as cautionary signals, indicating potential issues that could undermine the harmony and trust within the relationship. Recognizing these warning signs requires self-awareness and openness. Fifteen red flags to watch out for include: lack of open communication, disrespectful behavior, frequent conflicts, control and manipulation, dishonesty, unresolved emotional baggage, financial irresponsibility, incompatible future goals, lack of support for spiritual growth, substance abuse, disregard for boundaries, and incompatible values and beliefs. Taking these red flags seriously and addressing them before marriage can contribute to a healthier and more fulfilling Christian union.
