We understand that you're going through a difficult time, but we need to address this situation from a biblical perspective. First, we commend you for including Jesus Christ in your request, for it is only by His name that we can approach God.
First, let's consider what the Bible says about relationships. The Bible teaches that we should not be unequally yoked. This means that as Christians, we should not be in relationships with unbelievers.
Is your ex a believer in Jesus Christ? If they are not a believer, then pursuing a relationship with them is not aligned with biblical principles.
Do not be unequally yoked with unbelievers. For what fellowship has righteousness with lawlessness? What communion has light with darkness. 2 Corinthians 6:14 (WEB)
Second, the Bible teaches us to forgive as Christ forgave us. If there was wrongdoing in the past, you should forgive and move forward, but that does not necessarily mean that reconciliation in a romantic sense is the right path.
Let all bitterness, wrath, anger, outcry, and slander, be put away from you, with all malice. And be kind to one another, tenderhearted, forgiving one another, even as God in Christ forgave you. Ephesians 4:31-32 (WEB)
Third, it's important to seek God's will in all things, including relationships. Instead of focusing on getting your ex back, pray that God's will be done in both of your lives. If it is His will that you two be together, then trust that He will make a way. But if it is not His will, then trust that He has something better in store for you.
Do not 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. Romans 12:2 (WEB)
Let's pray together:
Dear Heavenly Father,
We come before You today in the name of Jesus Christ, lifting up this dear soul who is seeking Your will in their relationship. Lord, we ask that You guide them according to Your purposes and not their own. Help them to fully surrender to Your will and to trust in Your goodness and faithfulness.
If it is Your will, Lord, that this relationship be restored, then we ask that You make a way. We ask that You soften both of their hearts and draw them closer to You and to each other. But if it is not Your will, then we ask that You give them the strength to accept this and to move forward in faith.
We also pray for their jobs and family, Lord. We ask that You bless them abundantly and make Your face shine upon them. Give them peace and joy in the present moment, and help them to live in a way that honors and glorifies You.
In Jesus' name, we pray. Amen.
Remember, God's ways are higher than our ways, and His thoughts higher than our thoughts. Trust in Him, and He will direct your paths.
Be strong and courageous. Do not be afraid or terrified because of them, for the LORD your God goes with you; he will never leave you nor forsake you. Deuteronomy 31:6 (WEB)
Prayer Focus: God, Thank You for loving me. God, I ask You in Jesus’ name please bless me with everything that I stand in need of and everything You want me to have.
