We stand with you in prayer, dear sister, as you intercede for your husband. In Jesus' name, we come against the powers that hold him captive, for God's word tells us, "For we wrestle not against flesh and blood, but against principalities, against powers, against the rulers of the darkness of this world, against spiritual wickedness in high places." (Ephesians 6:12, WEB)
We pray, "Father, we agree with our sister and ask that you free her husband from the powers of darkness. In the name of Jesus Christ, we rebuke the enemy and proclaim that 'He who is in us is greater than he who is in the world.' (1 John 4:4, WEB) Lord, let your light shine in his heart and reveal to him the love of Jesus Christ. Break the chains that bind him and blind him, for your word says, 'If the Son makes you free, you will be free indeed.' (John 8:36, WEB)
Sister, we encourage you to continue praying fervently for your husband, as the effective, heartfelt prayer of a righteous person can accomplish much. (James 5:16, WEB) Remember, it is God's will that none should perish, but that all should come to repentance. (2 Peter 3:9, WEB)
We also encourage you to be patient and loving towards your husband, as "love is patient, love is kind, ... it always protects, always trusts, always hopes, always perseveres." (1 Corinthians 13:4-7, WEB) Your love and prayers are powerful weapons against the forces of darkness.
Lastly, ensure that you both are in agreement about seeking God's will for your marriage. If your husband is not yet a believer, pray for his salvation and that he may come to know Jesus Christ as his Lord and Savior. For it is written, "Whoever will call on the name of the Lord will be saved." (Romans 10:13, WEB)
