We understand that you are feeling really scared and in need of protection. Firstly, we want to assure you that God is your refuge and fortress, and He hears your prayers. In Psalm 91:1-2 WEB it says, "He who dwells in the secret place of the Most High will rest in the shadow of the Almighty. I will say of Yahweh, He is my refuge and my fortress; My God, in whom I trust."
We are concerned about the situation you are in with this man. It is clear that he is causing you harm and fear, and this is not God's will for you. We must address that God's design for relationships, especially for marriage is one that is honoring to God. Marriage is a lifelong commitment between one man and one woman. Ephesians 5:28-29 WEB says, "So husbands ought also to love their own wives as their own bodies. He who loves his own wife loves himself. For no man ever hated his own flesh; but nourishes and cherishes it, even as the Lord also does the assembly."
We must also rebuke the violence and mocking behavior you mentioned. This is not acceptable and it is not loving. God calls husbands to love their wives as Christ loved the church and gave himself up for her. 1 Corinthians 13:4-7 WEB says, "Love is patient and is kind; love doesn't envy. Love doesn't brag, is not proud, doesn't behave itself inappropriately, doesn't seek its own way, is not provoked, takes no account of evil; doesn't rejoice in unrighteousness, but rejoices with the truth; bears all things, believes all things, hopes all things, endures all things."
It is also important to note that you mentioned praying for him to come to know Jesus as his savior. This is very important, as it is only through Jesus Christ that we can be saved. Acts 4:12 WEB says, "There is salvation in none other, for neither is there any other name under heaven, that is given among men, by which we must be saved!" Jesus Christ came to save us from our sins and to give us eternal life. If you have not already, we encourage you to put your faith in Jesus Christ and to confess Him as your Lord and Savior.
As for your current situation, we pray that God will give you wisdom and guidance. It is not good or safe to stay with someone who is harming you, and we encourage you to seek help and support from local resources designed to assist in these situations. It does not seem like he will change and you should seek safety for yourself. Psalm 55:22 WEB says, "Cast your burden on Yahweh, and he will sustain you. He will never allow the righteous to be moved."
Let us pray together:
Dear Heavenly Father,
We come before You today, lifting up our sister in need of Your protection and guidance. We pray that You will surround her with Your angels and keep her safe from all harm. We ask that You will give her wisdom and discernment as she navigates this difficult situation, and that You will make a way for her to escape from this abusive relationship. We also pray for the man she mentioned, that You will bring him to a saving knowledge of Jesus Christ and convict him of his sins. We ask that You will soften his heart and bring him to repentance, so that he may be saved and transformed by Your grace. We pray all of this in the mighty name of Jesus Christ, our Lord and Savior. Amen.
Please take the necessary steps to ensure your safety and well-being. Trust in God to guide you and protect you during this time.
