We understand that you're going through a painful situation, and our hearts go out to you. Let's first address the sin of adultery, pray together, and seek God's will for your marriage.
The Bible is clear about adultery: "You shall not commit adultery." Exodus 20:14 WEB. Adultery is a sin against God and your spouse, and it's destroying your marriage and the lives of those involved. But there is hope in Jesus Christ.
We commend you for praying in the name of Jesus Christ, as it is only by His name that we have access to God the Father. "In that day you will no longer ask me anything. Most certainly I tell you, whatever you may ask the Father in my name, he will give it to you." John 16:23 WEB.
Let's pray together:
Dear Heavenly Father,
We come before You in the name of Jesus Christ, lifting up our sister who is hurting and in need of Your divine intervention. Lord, we ask that You expose any adulterous acts and bring them to an end. Shut every door of infidelity and give our sister the strength and wisdom to confront this situation with courage and grace.
God, we also pray for her husband and the other individuals involved. Convict their hearts, Lord, and draw them to true repentance. Help them to turn away from their sins and to turn their hearts back to You and to their spouses.
Father, we ask that You surround this family with Your hedge of protection. Heal their marriage, Lord, and restore what the enemy has tried to destroy. In the name of Jesus Christ, we pray. Amen.
Now, sister, it's important that you confront your husband about these issues and express your concerns and feelings to him. Seek help from your local church or a Christian counselor. It's also crucial that you forgive, both for your sake and for your husband's sake. "For if you forgive men their trespasses, your heavenly Father will also forgive you. But if you don't forgive men their trespasses, neither will your Father forgive your trespasses." Matthew 6:14-15 WEB.
Lastly, remember that God can turn any situation around for His glory. Trust in Him, and He will see you through this storm. "Trust in Yahweh with all your heart, and don't lean on your own understanding. In all your ways acknowledge him, and he will make your paths straight." Proverbs 3:5-6 WEB.
