We understand that you're going through a challenging time, and we want to assure you that God cares about your situation. We're called to address your needs in Jesus' name, and we will. First, let's pray:
Heavenly Father, we come before You lifting up our brother/sister who is in great need. We ask for Your divine intervention in their financial struggles, and we pray for Your provision and guidance in Jesus's name (John 14:13-14). We know that You are a good Father who gives good gifts to Your children (Matthew 7:11), and we trust that You will meet their needs according to Your glorious riches (Philippians 4:19). We also pray for their visa process in Jesus's name, that Your will be done and that doors will open for their future and education. We ask for Your peace to guard their heart and mind (Philippians 4:7), and we rebuke any spirit of fear, anxiety, or despair that may be tormenting them in Jesus's name. We will continue to pray for them. Now, let us encourage you with God's Word.
In Matthew 6:25-34 WEB, Jesus teaches us not to be anxious about our lives, what we will eat, or what we will wear. He reminds us that our heavenly Father knows that we need all these things. Instead, we are to seek first God's Kingdom and His righteousness, and all these things will be added to us. This doesn't mean that we shouldn't plan or work, but rather that our focus and trust should be in God, knowing that He ultimately provides for our needs.
We also want to remind you that God is faithful, and He will not let you be tempted beyond what you can bear (1 Corinthians 10:13 WEB). Even when things seem frightening, hold on to His promises. In addition, as you mention that you have tried everything humanly possible, be careful that you are not trusting your own abilities rather than God's. Also, you mention that you have prayed endlessly, screamed, and cried, but you did not mention the name of Jesus Christ. It is only in the name of Jesus that we have access to God the Father (John 14:6). Therefore, we strongly encourage you to put your faith in Jesus Christ, and pray in His name. If you need to be saved or have any questions about salvation, we will be happy to help.
Lastly, consider the words of the Apostle Paul in 2 Corinthians 12:9-10 WEB: "Most gladly therefore will I rather glory in my weaknesses, that the power of Christ may rest on me. Therefore I take pleasure in weaknesses, in injuries, in necessities, in persecutions, in distresses, for Christ's sake. For when I am weak, then am I strong."
Keep trusting in God, and keep praying. We will join you in prayer, trusting that God will make a way.
