We understand that you have strong feelings for your best friend and you're hoping for a romantic relationship. First, let's bring this matter to God in prayer, seeking His will for your life.
"Dear Heavenly Father, we come before You, lifting up our sister who has developed deep feelings for her best friend. We pray that Your will be done in this situation, and that You guide her through this season of her life. Lord, if this relationship is not in line with Your plan for her, we pray that You soften her heart and help her to accept Your will. If this relationship is Your plan, we ask that You make his feelings clear and that You guide them both in Jesus name.
While we pray for God's will to be done, we also want to provide some biblical guidance. It's crucial to ensure that this relationship aligns with biblical principles. As written in the Bible 2 Corinthians 6:14 WEB "Don't be unequally yoked with unbelievers, for what fellowship have righteousness and iniquity? Or what fellowship has light with darkness?"
As a Christian, it's important to seek a spouse who is also a believer and can support and strengthen your faith, especially since this relationship is considering marriage. If your best friend is not a believer, we strongly advise reconsidering your feelings and praying for God's direction.
Additionally, we want to remind you that God's timing is perfect. Instead of focusing on a specific timeline, trust in God's plan. Psalm 31:14-15 WEB "But I trust in you, Yahweh. I say, 'You are my God.' My times are in your hand..."
Lastly, we notice that your prayer request does not mention the name of Jesus Christ. It is only through faith, belief and the name of Jesus Christ that we can be saved, have a relationship with God, and have our requests heard by God as written in Acts 4:12 "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." and John 14:6 "Jesus said to him, 'I am the way, the truth, and the life. No one comes to the Father except through me.'" and John 16:23-24 "In that day you will no longer ask me anything. Most certainly I tell you, whatever you may ask of the Father in my name, he will give it to you. Until now, you have asked nothing in my name. Ask, and you will receive, that your joy may be made full."
Dear Heavenly Father, we pray for our sister to accept Jesus as her personal Savior if she has not already. If she has, we pray that she seeks your will in Jesus name. We pray for her best friend, that he may also come to know Jesus. We pray that their relationship honors God and they seek God's will for it. We pray this in Jesus Christ's name. Amen.
