We understand that you are seeking prayer for a relationship, and we want to help you align your requests with biblical principles. Firstly, we notice that you are using terms like "him" and "my ex" without explicitly defining the nature of these relationships. We assume that you are referring to a romantic interest and a former spouse or partner. However, we want to clarify that God's design for relationships is that they should be between a man and a woman in the context of marriage.
Your request focuses on emotions and reassurances, but let's remember that the foundation of any godly relationship is God Himself. It is encouraging that you mentioned praying in Jesus' name, as it is only through Him that we have access to God. 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.
Regarding your past relationship, it is important to ensure that it has been fully resolved in a biblical manner. If there was a marriage involved, it should be addressed according to God's principles. Remarriage after divorce is a complex issue, and God's Word provides guidance on this matter. In Matthew 5:32 WEB "But I tell you that whoever divorces his wife, except for sexual immorality, makes her an adulteress; and whoever marries a divorced woman commits adultery." and 1 Corinthians 7:10-11 WEB "But to the married I command-not I, but the Lord-that the wife not leave her husband (but if she departs, let her remain unmarried, or else be reconciled to her husband), and that the husband not leave his wife." If there was no marriage, then it is crucial to repent from any past immorality and pursue purity and forgiveness.
As you move forward, it is essential to build any new relationship on biblical principles. This includes ensuring that the relationship is pure and honoring to God. If you are not currently married, it is important to pursue this relationship with the intent of marriage, rather than merely as a boyfriend-girlfriend relationship. 2 Corinthians 6:14 WEB tells us, "Don't be unequally yoked with unbelievers, for what fellowship have righteousness and iniquity? Or what fellowship has light with darkness?" And in Ephesians 5:3 WEB it says, "But sexual immorality, and all uncleanness, or covetousness, let it not even be mentioned among you, as becomes saints"
Let us pray together:
Heavenly Father, we come before You in the name of Jesus Christ, seeking Your will and guidance. We pray for the person who submitted this request, that You would guide them according to Your Word. Help them to resolve any past relationships in a biblical manner and to pursue purity and forgiveness. Guide them in their current relationship, that it may be honoring to You and aligned with Your principles. Help them to trust in You and to build their relationship on the foundation of Your Word. Strengthen their bond in a godly manner, and reveal Your will to both of them. We ask this in Jesus' name, Amen.
We encourage you to study God's Word and seek His will for your relationships. May He guide you and bless you as you walk with Him.
