We understand that you're seeking God's will for your relationship, and we're here to pray and guide you according to biblical principles. Let's first bring your situation to God in prayer.
Father, we come before You in Jesus' name, lifting up our sister who is seeking Your will for her relationship. She has been with this man for seven years, and she has introduced him to her parents. However, her parents are not accepting of him. We pray that You will reveal Your will for this situation. We ask for Your wisdom and guidance. Help her to trust in You and to do what pleases You. We also pray for her parents, that they may be receptive to Your will and have a change of heart if that is what You want. We ask all of this in Jesus Christ's name. Amen.
It's important to remember that God's will is always in accordance with His Word. The Bible tells us, 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, Proverbs 3:5-6 WEB.
Regarding relationships, the Bible teaches us to be equally yoked with fellow believers, Do not be unequally yoked with unbelievers, for what fellowship have righteousness and iniquity? Or what fellowship has light with darkness? 2 Corinthians 6:14 WEB. You mentioned that he is a God-fearing man, which is encouraging. However, the fact that you've been together for seven years raises a concern. The Bible is clear about the sanctity of marriage and relationships. It tells us that sexual immorality should be explicitly discouraged and that it is God's will that you should be sanctified: that you should abstain from sexual immorality, 1 Thessalonians 4:3 WEB.
If you have been involved in a sexual relationship outside of marriage, we strongly encourage you to repent and seek God's forgiveness. It's also important to consider that a relationship should be a courtship with the goal of marriage to another Christian believer.
Moreover, the Bible commands us to honor our parents, Children, obey your parents in the Lord, for this is right. Honor your father and mother, which is the first commandment with a promise, that it may be well with you, and that you may live long on the earth, Ephesians 6:1-3 WEB. While their approval is important, remember that their desires should not supersede God's will. It's crucial to seek God's will first, and He will honor your obedience.
Lastly, it's important to pray in Jesus' name. It is by the name of Jesus that we have access to God. And in no other is there salvation, for neither is there any other name under heaven, that is given among men, by which we must be saved! Acts 4:12 WEB. If you haven't already, consider inviting Jesus into your life and the life of your courtship.
We encourage you to continue praying, studying the Word, and seeking godly counsel. God will make His will clear to you if you trust in Him.
