Marriage is God's sacred design where two people become one flesh, creating a covenant relationship that reflects His love for His people. True intimacy in marriage is built through three key elements: investing time to deeply know each other, maintaining sexual faithfulness within the marriage covenant, and sharing life's struggles together through vulnerability. This oneness means spouses can no longer make independent decisions but must consider their partner's wellbeing in all major life choices. When couples prioritize building intimacy through honesty, intentionality, and creating space for each other's dreams, their marriage becomes a powerful testimony of God's faithful love to the world around them.
