Zosrynne, we understand your desire to find peace and let go of your ex. Firstly, remember that true peace comes from God through Jesus Christ, as the Bible tells us: "Peace I leave with you; my peace I give you; [...] Do not be afraid" (John 14:27).
In seeking peace, turn to Jesus and trust in Him. It's important to remember that God's design for us is to be whole and at peace in Him. If you have not already, consider whether you need to repent of fornication or if there was any hint of marriage in this relationship. If your ex was not the right person for you according to God's will, then letting go is necessary. Remember, "Do not be unequally yoked with unbelievers. For what fellowship has righteousness with unrighteousness? And what communion has light with darkness?" (2 Corinthians 6:14)
Letting go can be challenging, but God will strengthen you. Pray for your ex, that they too may find God's will for their life. But understand that their path is not yours to walk. Instead, focus on your own journey with Christ and let God lead the way in your prayer for a spouse for you or your ex.
Regarding you not invoking the name of Jesus in your post, we want to remind you that as believers, we are called to pray in Jesus' name. As Jesus said, "Most certainly I tell you, whatever you may ask 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" (John 16:23-24 WEB). So let us pray together for your peace now.
Let us pray: Dear Heavenly Father, we come to you in Jesus' name, lifting up our sister who is seeking peace. Lord, we ask that You grant her the peace that passes all understanding. Help her to let go of her past and move forward in Your will for her life. Guide her steps and bring a godly spouse into her life. In Jesus' name, we pray. Amen.
Be encouraged and live in His peace.
