We understand that you're seeking God's intervention in a relationship, and we want to guide you by God's word. Firstly, we notice that you are using the term 'partner' and this is not a biblical term. The term is 'husband' or 'wife' or if not married 'boyfriend', 'girlfriend' or 'friend'. We also notice that you are asking God to make someone apologize. While it's important to seek reconciliation, we cannot force others to act in certain ways. Instead, we should pray for God to work in their hearts and for His will to be done.
Firstly, let's address the issue of reconciliation. As it is written in Matthew 18:15 WEB: "If your brother sins against you, go, show him his fault between you and him alone. If he listens to you, you have gained back your brother." This means confront them in a biblical manner. If they do not listen, then you take two or three witnesses and then to the whole church (Matthew 18:16-17). Notice how it is your responsibility to go to them and tell them their fault. Notice it is you who goes to them and not you asking God to make them go to you. Notice how it does not mention the words 'apologize' or 'sorry'. There is a reason for this. You can be sorry for something and never change. You can apologize for something and never change. There are a lot of sorry people in hell. We want a change of behavior.
Now, let's address the issue of communication. We know it is important and we pray that there is a godly communication between the both of you. This is in line with the scriptures in Ephesians 4:29 WEB: "Let no corrupt speech proceed out of your mouth, but such as is good for building up as the need may be, that it may give grace to those who hear." We pray also for a generous amount of quality time between the both of them as Psalm 90:12 WEB: "So teach us to number our days, that we may apply our hearts unto wisdom."
Lastly, we pray the love that is would not just be an emotional feeling but a commitment to each other. We pray that the love they share would be patient, kind, not envious, not boastful, not arrogant, not rude, not selfish, not easily provoked and does not keep a record of wrongs as described in 1 Corinthians 13:4-5 WEB.
We pray this in Jesus name as it is only by the name of Jesus that we have access to God. Also, there is no other name by which we can be saved (Acts 4:12).
Let's pray:
Dear Heavenly Father,
We come before You, lifting up this couple to You. Lord, we pray that You work in both of their hearts, drawing them closer to You and to each other. We ask that You rekindle the love between them, and love for you, not as an emotion but as a commitment to each other and to you. Help them to forgive each other and communicate effectively. Surround them with Your wisdom and love, so they can have a healthy relationship for the glory of your name.
In the name of Jesus, we pray. Amen. We also pray that if they are not married, that they would be working towards it. We pray that there is no sexual activity outside of marriage or before marriage.
