We understand that you're going through a difficult time and seeking God's will for your relationship. First, we want to assure you that God hears your prayers and cares about your heartache. We will pray with you and offer some biblical guidance.
First, we commend you for praying in Jesus' name, as it is only by His name that we have access to God's throne of grace. (Hebrews 4:16): "Let us therefore draw near with boldness to the throne of grace, that we may receive mercy, and may find grace for help in time of need."
Now, let's consider your situation in light of God's Word. It's important to remember that God's will should always be our primary concern, even when it's difficult to accept.
First Thessalonians 4:3-5 (WEB): "For this is the will of God: your sanctification, that you abstain from sexual immorality, that each one of you know how to possess himself of his own vessel in sanctification and honor, not in the passion of lust, even as the Gentiles who don't know God."
Romans 12:2 (WEB): "Don't be conformed to this world, but be transformed by the renewing of your mind, so that you may prove what is the good, well-pleasing, and perfect will of God."
From your prayer, it seems that you are in a state of distress because of your beloved. While it's natural to desire a loving relationship, it's crucial to ensure that this relationship aligns with biblical principles. If the relationship is not honoring God, it might be causing more harm than good.
If you are not married but are in courtship, remember that God calls us to remain pure and holy. If this is a godly courtship, then continue to pursue it with marriage in mind. If not, it might be best to reevaluate the relationship.
Regarding your feelings of desolation, remember that God is always with you, even in your darkest hours. Psalm 34:18 (WEB): "Yahweh is near to those who have a broken heart, and saves those who have a crushed spirit."
Let's pray together:
Dear Lord, we come before You, lifting up our brother/sister in Christ who is experiencing deep emotional pain. We ask for Your healing touch on his/her heart and soul. Lord, if it is Your will for this relationship to continue, we pray that You soften her heart and remove any lies and disinterest. If it is not Your will, give him/her the discernment, strength, and confidence to accept and embrace Your plan.
Lord, we also pray for peace to fill his/her heart, driving out all desolation. Remind him/her of Your constant presence and love. In Jesus' name, we pray. Amen.
Be strong and courageous. When you call on the name of Jesus you are calling on the name of the Lord. The name of Jesus is the only name by which we can be saved.
