We are truly sorry to hear about the challenges you and your family are facing. Let's bring your situation before the Lord in prayer and seek His guidance and provision.
Firstly, we commend you for trusting in the Lord and recognizing that He often allows us to exhaust our efforts before He steps in to help. This is a testament to your faith, and we encourage you to remain steadfast.
As for the relationship discussed: Marriage is indeed a holy institution that should not be taken lightly. Therefore, make sure that you can sustain a marriage for life and do not engage in any impurity before or during marriage.
Let us pray:
Dear Heavenly Father,
We come before You today in the name of Jesus, lifting up this family in their time of need. Lord, You know the struggles they have been through, and the challenges they are facing now. We ask for Your divine intervention, that You would provide a safe and stable home for them.
Lord, we also pray for the marriage discussed. Guide them in Your wisdom, and help them to make decisions that honor and glorify You. Heal any brokenness and restore what has been lost especially if this was not a marriage in your eyes.
Father, we ask that You would open the heavens and pour out Your blessings on this family. Provide for their needs, both physical and spiritual, and give them a supernatural peace that surpasses all understanding.
Lord, we trust in Your goodness and mercy. We know that You are a God who hears and answers prayers, and we believe that You will make a way where there seems to be no way.
In Jesus' name, we pray. Amen!
Remember, the Lord is close to the brokenhearted and saves those who are crushed in spirit. (Psalm 34:18 WEB) Trust in Him, and He will act.
Also, consider the words of Jesus in Matthew 6:25-34 (WEB), "Therefore I tell you, don't be anxious for your life: what you will eat, or what you will drink; nor yet for your body, what you will wear. Isn't life more than food, and the body more than clothing? See the birds of the sky, that they don't sow, neither do they reap, nor gather into barns. Your heavenly Father feeds them. Aren't you of much more value than they? 'Which of you, by being anxious, can add one moment to his lifespan? Why are you anxious about clothing? Consider the lilies of the field, how they grow. They don't toil, neither do they spin, yet I tell you that even Solomon in all his glory was not dressed like one of these. But if God so clothes the grass of the field, which today exists, and tomorrow is thrown into the oven, won't he much more clothe you, you of little faith? Therefore don't be anxious, saying, 'What will we eat?', 'What will we drink?' or, 'With what will we be clothed?' For the Gentiles seek after all these things, for your heavenly Father knows that you need all these things. But seek first God's Kingdom, and his righteousness; and all these things will be given to you as well. Therefore don't be anxious for tomorrow, for tomorrow will be anxious for itself. Each day's own evil is sufficient."
Lastly, we want to encourage you to always pray in the name of Jesus. It is by His name that we have access to the Father, and it is by His name that we are saved. If you have not already, consider the words of Acts 4:12 (WEB), "There is salvation in none other, for neither is there any other name under heaven, that is given among men, by which we must be saved!" If you have not accepted Jesus as your Lord and Savior, we encourage you to do so today. Believe in Him, confess your sins, and commit your life to Him. He will save you and give you eternal life.
