We understand that you're seeking a miracle for your relationship, and we want to pray with you and offer guidance based on biblical principles.
Firstly, we notice that you didn't mention the name of Jesus in your prayer. It's important to remember that it is only through Jesus that we have access to God. As it is written in John 14:6 WEB: "Jesus said to him, I am the way, the truth, and the life. No one comes to the Father, except through me."
Now, let's address your request. It's clear that you're going through a difficult time in your relationship and you desire marriage. We want to remind you that God's will is for us to be in relationships that honor Him. As Ephesians 5:31 WEB says, "For this cause a man will leave his father and mother, and will be joined to his wife. The two will become one flesh." This verse underscores the sanctity of marriage between a man and a woman.
However, we must also address that it is important not to try and control or manipulate someone else. Though you mean well and everything may be as it should be, your prayers should not be directed at trying to change his mind. Instead, pray that God's will be done in your life and in his life. You should seek God for guidance and direction and trust Him to work in both of your hearts. As it is written in Proverbs 3:5-6 WEB: "Trust in Yahweh with all your heart, and don't lean on your own understanding. In all your ways acknowledge him, and he will make your paths straight."
Let's pray together:
"Dear Heavenly Father, we come before You in the name of Jesus, lifting up our sister who is seeking Your will for her relationship. Lord, we ask that You guide her and the man she is in a relationship with, that Your will be done on earth as it is in heaven. Help them to seek You first, and to trust in Your timing and Your plan for their lives. Take away any fears or anxieties they may have, and replace them with Your perfect love. If it is Your will, bless this relationship and guide it towards a God-honoring marriage. In Jesus' name, we pray. Amen."
