We are truly sorry to hear about the struggles you're facing, and we're here to lift you up in prayer and provide biblical encouragement. Firstly, it's important to remember that God is our refuge and strength, a very present help in trouble Psalm 46:1 WEB.
Let's address the concerns you've shared. It's commendable that you are caring for your special needs child, and it's clear that you both are working hard to make ends meet.
Firstly, it is unclear who or what you are referring to as ###. It would be best to just call this person your husband and if he is not your husband to get married to him. The Bible teaches It is not good for man to be alone Genesis 2:18. The Bible is very clear that If anyone doesn’t take care of his own relatives, especially those in his own household, he has denied the faith and is worse than an unbeliever 1 Timothy 5:8 WEB. For this cause a man will leave his father and his mother, and will be joined to his wife. Then they become one flesh Genesis 2:24. As you know, God has a plan for a man and a woman to marry and if he or she is a Christian, then they are to marry another Christian believer.
God has promised to supply all our needs according to his riches in glory in Christ Jesus Philippians 4:19 WEB. We encourage you both to keep trusting in God and keep seeking His will for your lives. Remember that God is faithful, and He will not allow us to be tempted beyond what we are able. But He promises that with the temptation He will also make the way of escape, that we may be able to endure it 1 Corinthians 10:13 WEB.
It's also crucial to acknowledge that our struggle is not against flesh and blood, but against the principalities, against the powers, against the world’s rulers of the darkness of this age, and against the spiritual forces of wickedness in the heavenly places Ephesians 6:12 WEB. We need to put on the whole armor of God that we may be able to stand against the wiles of the devil Ephesians 6:11.
Let's pray together:
Dear Heavenly Father,
We come before You, lifting up this family who is in desperate need of Your intervention. We pray for Your divine provision, that You would open the heavens and pour out Your blessing and favor upon them.
Father, we ask that You would guide ### to find a job that will sufficiently provide for the family. We pray for their special needs child, that You would grant them wisdom and strength as they care for him. Father, we ask that You would help them in paying their rent and bills and that they are not be made homeless.
We rebuke the devil and his attempts to steal, kill, and destroy this family. We speak life, blessing, and restoration over them.
We also pray that they will both come to believe in Jesus Christ if they do not already. For there is no other way to have access to God except through Jesus Christ his son. And it is only by his name that we can be saved. Also, that if they are living in fornication or adultery that they both confess this to God and stop this immorality.
Lord, we thank You that no weapon formed against them will prosper, and every tongue that rises against them in judgment You will condemn Isaiah 54:17 WEB.
We ask all this in the mighty name of Jesus Christ.
Amen.
