We are here to intercede for your brother and to seek God's will together in Jesus' name. Firstly, it is important to acknowledge that God cares about our financial needs and wants us to trust Him with all aspects of our lives.
Jesus Himself said in Matthew WEB:
But seek ye first the kingdom of God, and his righteousness; and all these things shall be added unto you.
Take therefore no thought for the morrow: for the morrow shall take thought for the things of itself. Sufficient unto the day is the evil thereof.
We should first pray that your brother seeks God and His righteousness.
Your brother should do his part by being a responsible steward of his finances and by working diligently.
In 2 Thessalonians WEB it says:
For even when we were with you, we commanded you this: If any will not work, neither let him eat.
For we hear that there are some who walk among you disorderly, working not at all, but are busybodies.
Now them that are such we command and exhort by our Lord Jesus Christ, that with quietness they work, and eat their own bread.
Let us pray for your brother:
"Father, we come before You in Jesus' name, lifting up our brother who is in financial bondage. We pray that You would help him to seek You first and Your righteousness. Help him to trust Your provision and be faithful with what he has.
Open the doors for a good job that would allow him to provide for his family. Give him the wisdom to manage his finances according to Your will. Help him to be free from the bondage of debt.
We rebuke any spirits of greed, and poverty in Jesus' name. Help him to work as if working unto you and not unto men, in Jesus' name. We pray that he would be able to provide for his family and be a blessing to others. We ask all this in Jesus Christ's name. Amen."
We also remind you that it is only by the name of Jesus that we have access to God. As it is written in John WEB:
Jesus saith unto him, I am the way, the truth, and the life: no man cometh unto the Father, but by me.
And in Acts WEB:
This Jesus hath God raised up, whereof we all are witnesses.
Therefore being by the right hand of God exalted, and having received of the Father the promise of the Holy Ghost, he hath shed forth this, which ye now see and hear.
For David is not ascended into the heavens: but he saith himself, The LORD said unto my Lord, Sit thou on my right hand,
Until I make thy foes thy footstool.
Therefore let all the house of Israel know assuredly, that God hath made that same Jesus, whom ye have crucified, both Lord and Christ.
Neither is there salvation in any other: for there is none other name under heaven given among men, whereby we must be saved.
