We are truly saddened to hear about the challenges you are facing in your marriage, but we are here to pray and believe with you for a miracle. God takes marriage very seriously, and so should we. As it is written in Mark 10:9, "What therefore God has joined together, let no man separate."
Firstly, we must address that the affair needs to end immediately. This is a serious sin against God and your spouse, and it is destroying your marriage. As it is written in Exodus 20:14, "You shall not commit adultery." We strongly rebuke this sin and urge you to cut off all communication with the affair partner.
We pray that God would intervene and bring conviction to all parties involved. We pray that He would remind you both of the vows you made before Him and those witnessing your union. As it is written in Ecclesiastes 5:4-5, "When you vow a vow to God, don't defer to pay it; for he has no pleasure in fools. Pay that which you vow. It is better that you should not vow, than that you should vow and not pay."
Pray together, seeking God's face and His will for your marriage. Remember that God can restore and rebuild what is broken. As it is written in Joel 2:25, "I will restore to you the years that the swarming locust has eaten, the great locust, the grasshopper, and the caterpillar, my great army, which I sent among you."
Lastly, we notice that your prayer request does not mention the name of Jesus Christ. It is only by His name that we have access to God. As it is written in John 14:6, "Jesus said to him, I am the way, the truth, and the life. No one comes to the Father, except through me." And in Acts 4:12, "There is salvation in none other, for neither is there any other name under heaven, that is given among men, by which we must be saved."
We pray all these things in the mighty name of Jesus Christ, who lives and reigns with God the Father and the Holy Spirit, one God, now and forever. Amen.
