God's teachings about marriage are foundational to Christian beliefs and are found throughout the Bible. Here are key principles and Bible verses about marriage:

1. Marriage is God’s Design

Genesis 2:24 (NIV): "That is why a man leaves his father and mother and is united to his wife, and they become one flesh."

Matthew 19:4-6 (NIV): "Haven't you read," he replied, "that at the beginning the Creator 'made them male and female,' and said, 'For this reason a man will leave his father and mother and be united to his wife, and the two will become one flesh'? So they are no longer two, but one flesh. Therefore what God has joined together, let no one separate."

2. Mutual Love and Respect

Ephesians 5:25 (NIV): "Husbands, love your wives, just as Christ loved the church and gave himself up for her."

Ephesians 5:22-24 (NIV): "Wives, submit yourselves to your own husbands as you do to the Lord. For the husband is the head of the wife as Christ is the head of the church, his body, of which he is the Savior."

Ephesians 5:33 (NIV): "However, each one of you also must love his wife as he loves himself, and the wife must respect her husband."

3. Commitment and Faithfulness

Hebrews 13:4 (NIV): "Marriage should be honored by all, and the marriage bed kept pure, for God will judge the adulterer and all the sexually immoral."

Malachi 2:16 (NIV): "I hate divorce," says the Lord, the God of Israel, "and the one who is guilty of violence," says the Lord Almighty. So be on your guard, and do not be unfaithful."

4. Unity and Partnership

Ecclesiastes 4:9-12 (NIV): "Two are better than one, because they have a good return for their labor: If either of them falls down, one can help the other up. But pity anyone who falls and has no one to help them up."

5. Marriage as a Reflection of Christ’s Relationship with the Church

Ephesians 5:31-32 (NIV): "For this reason, a man will leave his father and mother and be united to his wife, and the two will become one flesh. This is a profound mystery—but I am talking about Christ and the church."

6. Roles in Marriage

1 Corinthians 7:3-5 (NIV): "The husband should fulfill his marital duty to his wife, and likewise the wife to her husband. The wife does not have authority over her own body but yields it to her husband. In the same way, the husband does not have authority over his own body but yields it to his wife."

7. Lifelong Covenant

Mark 10:9 (NIV): "Therefore what God has joined together, let no one separate."

These verses provide a biblical foundation for understanding God’s design for marriage, emphasizing love, unity, respect, and faithfulness.
