We understand your concern for your friend "R" and the struggles you're both facing. In these difficult times, it's important to remember that God is our refuge and strength, a very present help in trouble (Psalm 46:1, WEB).
Firstly, let's address the fear and doubt that have crept into your hearts. The Bible tells us, "Don’t be anxious for anything, but in everything, by prayer and petition with thanksgiving, let your requests be made known to God. And the peace of God, which surpasses all understanding, will guard your hearts and your thoughts in Christ Jesus." (Philippians 4:6-7, WEB)
For "R", who has lost their apartment and car, we pray:
"Dear Lord Jesus Christ, we lift up 'R' to you. They trusted in you and took a step of faith, but now they're facing hardship. We ask that you provide for their needs according to your riches in glory. May they find comfort in your promise that you will never leave them nor forsake them (Hebrews 13:5, WEB). Please guide them to a new job, a safe place to live, and restore what they have lost. Strengthen their faith in this trial, and let it be a testimony of your goodness. In Jesus' name, we pray."
For you, who are also facing trials and feeling doubtful, we pray:
"Dear Lord Jesus, we lift up our dear friend who is struggling with doubt and fear. We ask that you renew their faith and help them to trust in you again. Give them the strength to endure their current job or guide them to a new one if that's your will. Remind them that your plans are for their welfare and not for harm, to give them a future and a hope (Jeremiah 29:11, WEB). Help them to fix their eyes on you, the author and perfecter of their faith (Hebrews 12:2, WEB). In Jesus' name, we pray."
Lastly, we want to encourage both of you to cling to God's promises. Even when we don't understand why things happen, we trust that God works all things together for good for those who love him, who are called according to his purpose (Romans 8:28, WEB). Keep supporting each other, and remember that our faith is not in our circumstances, but in Christ Jesus who overcame the world (John 16:33, WEB).
We noticed that you mentioned Jesus in your request, which is wonderful. It's only through his name that we can come to the Father (John 14:6, WEB). If there's any doubt about his love and power, we encourage you to keep seeking him, for he promises that those who seek him with all their heart will find him (Jeremiah 29:13, WEB).
