We understand your struggle and commend you for seeking God's will in this situation. The Bible teaches us to honor our parents, but it also teaches us that each person is responsible for their own family. Your father's actions and words seem to be more about his own desires than your well-being, which can be challenging to deal with.
Firstly, let's address the issue of marriage. Marriage is a blessing from God, and it is not good for man or woman to be alone. In Genesis 2:18 WEB it says, It is not good that the man should be alone. I will make him a helper comparable to him. God wants us to have loving marriages that reflect His love for His church. Your father should not be discouraging you from this.
Secondly, your father's reliance on you and his desire for you to remain unmarried to serve him is selfish and not in line with biblical principles. In Ephesians 5:23 WEB it says, A man shall leave his father and his mother, and shall be joined to his wife. They will be one flesh. This shows that the man will follow God's design for the family. We leave our parents and follow God's design.
Thirdly, it is normal to feel ashamed and angry when a parent behaves in a selfish manner. However, we must remember that God calls us to honor our parents, even when it is difficult. In Ephesians 6:2 WEB it says, You shall honor your father and mother. This is the first commandment with a promise.
However, honoring your father does not mean allowing him to control your life or emotions. You can honor him by showing him love and respect, but you should not allow his selfish desires to dictate your life.
Let's pray for you and your father.
Heavenly Father, we come before You in Jesus' name, lifting up this daughter and her father. Lord, You know the struggle she is facing, and You understand her feelings of anger and shame. Help her to release these feelings to You and to forgive her father for his selfishness. Give her the strength to honor her father while also setting appropriate boundaries. Open her father's eyes to his selfishness and help him to see the error of his ways. Change his heart and mind, and help him understand that this daughter's choices should be about what is best for her, not him. Help her father to apologize, ask for forgiveness, and show love and support. Guide this daughter as she seeks Your will for her life and help her to find a godly spouse if that is Your will. In Jesus' name, we pray. Amen.
Lastly, we encourage you to set boundaries with your father. It is important to communicate with him about how his actions make you feel and set boundaries to protect your emotional well-being. Seek godly counsel and support during this time, and trust that God will guide you through this situation. Remember that God's will is for you to have an abundant life, and He will guide you and your father to this outcome if you both submit to His will.
