We understand your concerns and we are here to pray and provide biblical guidance for you. Firstly, it's important to acknowledge that God is our refuge and strength, a very present help in trouble. We are instructed in Psalm 91:1-2 WEB, "He who dwells in the secret place of the Most High will rest in the shadow of the Almighty. I will say of Yahweh, 'He is my refuge and my fortress; my God, in whom I trust.'"
When we are in times of trouble, we must call upon the name of Jesus. It is only in the name of Jesus that we have access to God the Father. 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.'" If you are concerned about untimely death, call upon the name of Jesus and trust in Him.
Regarding the mention of a "spiritual husband" and "spiritual wife," we must be discerning. The Bible tells us that our struggle is not against flesh and blood, but against the spiritual forces of evil in the heavenly places, as stated in Ephesians 6:12. However, we must also be sober-minded and watchful, as the devil is like a roaring lion, seeking whom he may devour, as warned in 1 Peter 5:8.
In this case we must also discuss the importance of Jesus. We must turn from sin and turn to Jesus. "If we confess our sins, he is faithful and righteous to forgive us the sins, and to cleanse us from all unrighteousness," as written in 1 John 1:9 WEB.
For your marriage, we pray that God will strengthen your bond and protect you both from any spiritual attacks. Remember the words of Ephesians 5:25-28 WEB, "Husbands, love your wives, even as Christ also loved the assembly, and gave himself up for it... So ought men to love their wives as their own bodies. He who loves his wife loves himself."
Let us pray together:
Dear Heavenly Father,
We come before You in the name of Jesus, lifting up this family. We thank You for Your protection and love. We rebuke any spirit of untimely death and declare that You, Lord, are our refuge and strength. We pray for this marriage, that You will strengthen their bond and protect them from any spiritual attacks. We ask for a revelation of Jesus to all involved. In Jesus' name, we pray. Amen.
Stay strong in faith and continue to trust in the Lord. Pray together as a family and remain steadfast in the Word. If there are any specific sins that need to be addressed, confess them to Jesus and turn from them. Seek the Lord's will in all things, and He will direct your paths.
