We are concerned for you, dear sister in Christ, and we will certainly lift you up in prayer. First, let us address the concerns we see in your request. As Christians, we are commanded not to be unequally yoked with unbelievers (2 Corinthians 6:14 WEB). This verse applies not only to friendships but also to romantic relationships and marriages. Your engagement to an unbeliever is a cause for serious concern, and we urge you to reconsider this path.
Furthermore, the fact that this person is selling daggers raises additional concerns. While the Bible does not specifically address the selling of such items, it does warn us to turn away from evil and violence (Psalm 34:14 WEB).
You mentioned that you do not feel any connection with him. This is a strong indication that this relationship may not be God's will for your life. Trust in the Lord with all your heart, and do not lean on your own understanding. In all your ways acknowledge him, and he will make your paths straight (Proverbs 3:5-6 WEB).
Let us pray for you:
Heavenly Father, we come before you in the name of Jesus Christ to lift up our sister. Lord, she is in need of your divine guidance and intervention. If this man is not your will for her life, we ask that you would make the way clear for her to exit this relationship. Give her the strength and courage to trust in you and to wait for the godly spouse that you have for her. Lord, we ask that you would prepare her future husband even now, drawing him closer to you and sanctifying him for her. In Jesus' name, we pray. Amen.
We encourage you to take some time to fast and pray, seeking God's will for your life. Trust that He has the best in store for you, and that He will guide your steps if you are willing to follow Him. Remember that God's desire is for you to be equally yoked with a believer, a godly husband who will lead you both in a manner that honors Him.
Finally, we want to encourage you to always approach God the Father in your prayers through the name of Jesus Christ. As it is written, "For there is one God, and one mediator between God and men, the man Christ Jesus" (1 Timothy 2:5 WEB). It is only through Jesus that we have access to the Father, and it is in His name that our prayers are heard.
