We stand with you in prayer over your brother and his wife and we share your grief over this sin that is tearing at a holy covenant. We hear your cry for his eyes to be opened and for this adultery to stop immediately and we join you in asking God for conviction, repentance and restoration.
God established marriage as a lifelong covenant between a man and a woman, and He calls it honorable and undefiled. What therefore God has joined together, let no man separate, Matthew 19:6. Let marriage be held in honor among all, and let the bed be undefiled: but God will judge the sexually immoral and adulterers, Hebrews 13:4. Your brother's affair is not a mistake or a simple failing, it is adultery, it is sexual immorality outside the marriage bed, and Scripture is clear that he who commits adultery with a woman is void of understanding. He who does it destroys his own soul, Proverbs 6:32. We must call it what God calls it so that repentance can be real.
You rightly discerned a spirit of blindness and lust at work. Lust conceives sin and sin brings forth death when it is allowed to remain, as James 1:14-15 teaches, and the enemy blinds minds to keep a person from seeing the destruction he is causing. In whom the god of this age has blinded the minds of the unbelieving, that the light of the Good News of the glory of Christ, who is the image of God, should not dawn on them, 2 Corinthians 4:4. Flee sexual immorality. Every sin that a man does is outside the body, but he who commits sexual immorality sins against his own body, 1 Corinthians 6:18. Your brother is sinning against God, against his own body and soul, against his wife and against his family, and he is blinded to the pain he is causing his wife who is now suffering deeply.
We rebuke together in the name of Jesus Christ the spirit of lust, fornication and adultery that has taken hold of your brother. We command that deceiving and blinding influence to be broken and we ask the Holy Spirit to bring piercing conviction and godly sorrow that leads to repentance. Be subject therefore to God. But resist the devil, and he will flee from you, James 4:7. We pray that your brother will submit himself to God, resist this temptation, cut off all contact with the other person completely and flee from this immorality without delay or excuse.
We lift up his wife to the Lord who sees her tears and knows her hard time. We pray that God will be near to her as the One who is close to the brokenhearted and that He will surround her with comfort, strength and godly counsel. We pray that your brother will remember his vows and obey the command, Husbands, love your wives, even as Christ also loved the assembly, and gave himself up for it, Ephesians 5:25. That love is sacrificial, faithful and exclusive.
We pray together now. Father in heaven, in the name of Jesus Christ we come before Your throne of grace for this brother and his marriage. Lord, open his eyes and remove the blindness of lust that has deceived him. Convict his heart deeply of his adultery and grant him no peace until he repents. Cause him to hate this sin as You hate it and to turn from it completely. Forgive him as he confesses, for if we confess our sins, he is faithful and righteous to forgive us the sins, and to cleanse us from all unrighteousness, 1 John 1:9. Lord, break every ungodly tie and end this affair immediately. Turn his heart fully back to his wife and to You. Heal the wounds in his wife's heart, comfort her, give her wisdom and protect her from bitterness. Restore what the enemy has tried to destroy and rebuild this marriage on truth, faithfulness and Your Word. Give this family member who is interceding boldness to speak the truth in love and perseverance to keep praying. We ask all this in the mighty name of Jesus Christ, our only Savior and our access to You, amen.
We encourage you to continue to intercede faithfully and to urge your brother in love to seek immediate pastoral counsel and accountability, to end all contact with the other woman and to pursue repentance and reconciliation with his wife. God is able to forgive and to restore when there is genuine repentance, and we pray with you that he will choose life and obedience and return to his wife and to the covenant he made before God.
