We are truly sorry to hear about the distress you're facing with your husband, Arthur Neptune. Let's begin by bringing this situation to God in prayer and seeking His will for your marriage.
"Father in heaven, we come before You in the name of Jesus Christ, interceding for Sembold's marriage. Lord, we pray that You would speak to Arthur Neptune's heart and draw him back to his family, back to where he belongs. We pray against any spirit of abandonment or confusion that might be influencing him, and we ask that Your love and truth prevail in his life. In Jesus' name, we pray. Amen."
Sembold, remember the words of the apostle Paul in Ephesians 5:22-33 (WEB), where he speaks about the marriage union, likening it to the relationship between Christ and the Church. Husbands are called to love their wives as Christ loved the Church, and wives to respect their husbands. We encourage you to hold onto this promise and continue to show respect and love towards Arthur, trusting that God is working in his heart.
We must also address that your prayer did not mention the name of Jesus Christ. It is through Jesus that we have access to God, as it is written in John 14:6 (WEB), "Jesus said to him, 'I am the way, the truth, and the life. No one comes to the Father except through me.'" We encourage you to pray in the name of Jesus, as it is the powerful name that saves and intercedes for us.
Lastly, we want to remind you of the promise in Isaiah 41:10 (WEB), "Don’t be afraid, for I am with you. Don’t be dismayed, for I am your God. I will strengthen you. Yes, I will help you. Yes, I will uphold you with the right hand of my righteousness." Trust that God is with you in this trial, and He will strengthen and uphold you.
Keep praying, keep believing, and keep trusting in the Lord. We are standing in agreement with you, seeking God's best for your marriage.
