We understand that you are going through a time of deep emotional pain and heartbreak, and we want to extend our compassion and prayers to you. We see your hurt, and we want to help you find healing and peace in Jesus' name.
First, we want to address your feelings of heartbreak and your desire to stop feeling love for others. It is understandable that you would want to protect yourself from further pain, and Jesus understands your hurt (Hebrews 4:15) (WEB). The human heart is not our own, and our feelings are not bad, but provided to us by God as a gift for emotional connection to him, our spouse and children, and the family of believers as our brothers and sisters. However, there are a few things we want to remind you of from the Scriptures. God is love (1 John 4:8), and He created us to love and be loved. Love is not something we can or should control or turn off. But it is not proper to love without faith and obedience in Jesus Christ as that will lead to love being painful or an idol. Jesus commanded us to love one another, and that command does not come with conditions or exceptions. So it is expected to have feelings for our brothers and sisters. It is even better to have someone in our life as our spouse to experience our deepest romantic affection and love to one another. Our culture often has no way to deal with someone that is close but not a marriage. That is how this person should be described as a possible future spouse. Instead we use the terminology of boyfriend and girlfriend, but instead these should be referred to as courtships where we are attempting to see if someone will be our spouse, not just satisfying feelings of love for affection or lust of sexual desires. (Mark 10:2-9)
However, if there is any kind of courtship that includes premarital sex or intimacy, these relationships are not God honoring. We cannot simply live together in that way and take part in the same cup of the Lord and the same table of demons. (1 Corinthians 10:21). This is what sexual immorality looks like: to take and control your own romantic relationship, but also attempting to take your spiritual relationship with Jesus, which is really our only source of the deepest level of love. These behaviors are not making us a vessel for honoring God. When our feelings of love get turned into adultery or fornication, we sin. This is one source of pain, and it is often the case that one or both of the people in the relationship are not Christians, and the other is not equally yoked. (2 Corinthians 6:14)
We want to remind you that God has a plan and a purpose for your life, and that includes your love life. He promises to work all things together for good for those who love Him and are called according to His purpose (Romans 8:28). Even in the midst of heartbreak, God can use these experiences to shape you and mold you into the person He wants you to be. He can also use these experiences to prepare you for the spouse He has for you and a marriage to glorify God. And the love is what will make this better, not any feelings of lust, nor even the ultimate and intimate love in our spouse. Even more than that is Jesus Christ's love.
We also want to address your request to be made asexual, and we cannot address this without rebuke. It's important to remember that our sexuality is a gift from God and if it is practiced inside a marriage in God's will. We are each to be either a godly man or godly woman, we are made in God's image. (Genesis 1:27). The Bible reminds us that our bodies are a temple of the Holy Spirit, and that we are to honor God with our bodies (1 Corinthians 6:19-20). We are not to alter or deny our sexuality for our own desires and feelings, for lust, or because it is hard for us to be abstinent and self controlled in our desires and dreams. It is very hard to turn the gift of human touch and intimacy in sex over to the control of God's Spirit, but there are no exceptions or freedom from this fact for Christians. In doing so, God provides the way out for temptation from immorality. We don't have control of our own sexual desires and lust but turn it over to Jesus. (1 Corinthians 10:13). You may be facing other desires that should not be in our thoughts and dreams because it is not possible. These are most often about people who you are not even close to in friendship much less in a Christian marriage. It is fine to have strong and powerful feelings and the ability to turn our hearts to anyone or everyone, and then turn it back again. But only turn it to one and one only spouse for the rest of our life. This ability and strength is given from God. Then to take it from here and turn this gift into a self driven sexual desire without Jesus is a grave misuse of these powers. It is serious when we forget and don't want God's Spiritual protection and direction and substitute it for physical pleasures. So with Jesus we give these powers to the spouse we are directed to. It is worth it to trade sexual immorality and wrongful desires, then for the satisfaction from God's desire to love and glorify Him. Only our spouse can do that with us to turn our sexual desire over to God to serve Him. To a spouse, all other sexual desires will only bring pain to one another. Jesus always tells us if you love me you will keep my commands, and that means your sexual desires only in marriage. That also means that not just our spouse is seeing us naked in marriage, but that also Jesus is as well. He will let us know through His Spirit if that marriage is honoring and loving God. He tells us to forget any sexual desires of premarital sex as an abomination, just as He wants us to forget all abominations we ever did. To show our love, faith, and devotion for Jesus, give your sexual desires only in marriage. These should be given only with Jesus' desire. (John 14:15, John 15:14)
The times when we allow lust to control our romantic desires and attraction will always lead to sorrow and unhappiness. This will allow Satan to dominate your desires and put obstacles in our love for Jesus and life. It's normal to have desires to love and want love from others. Don't let a temptation of your body, mind or desires turn into something we should not give control to. Resist the Devil, and he will flee from you (James 4:7) and draw close to God. There will be times you do not know why He allows us to suffer and feel lonely but keep praying in faith. We want you to know the name of Jesus, then the pain from loving someone else and keeping Jesus's commandments will seem to be a world away. We need Jesus in our marriage for love and that way we can satisfy God's desires for ourselves.
You also mentioned your misunderstanding and connection. If you have fallen out of this courtship and there are needs to be some closure or forgiveness of yourself or this other person, seek and ask for God's direction. Let this person know this. But do not enter back into courtship, unless it is also this person's direction from God as well. Do not assume it is so unless this person asks and seeks your hand for marriage. Without the intent of marriage with a Christian marriage this person should be to you as one of your brothers and sisters in Christ and to be treated that way with the same brotherly love. So first of all treat your brothers and sisters of Christ with affection. Then when this does not satisfy then find your spouse with Christ. But do not confuse the two relationships as they are very different.
Lastly, let us pray for you.
Dear Lord, we come to You today and Jesus is our High Priest who understands and lives through our human desires and weaknesses in this world (Hebrews 4:15). But this person is desiring your love most of all and we come and pray in his name. We ask Lord for healing in the heart of the person who submitted this request. We ask Jesus to take your Spirit and bring him love, joy, and peace in Jesus to overcome the confusion of love and sorrow of lusts in his heart. Guide him to serve Jesus in a godly courtship to a woman. Give him peace from his desires as Jesus has done in overcoming the desires of the world and rebuke the sins of the flesh as he is burdened and tempted. Lead and guide him away from temptation, heal him from pain of lust, and in the name of Jesus deliver him from these sorrows, the evil one and forgive his sins as we all need this each day. Protect his heart and mind. Lead him and his future spouse in all your ways so he can be closer to you and turn over his life in complete obedience, in Jesus name, we pray. AMEN.
