We understand your struggles and we're here to support you in prayer and guidance. Let's first address your physical and spiritual healing.
You mentioned that you're unsure if God can heal you. Remember, Jesus said, "All things are possible for him who believes." (Mark 9:23 WEB) We encourage you to meditate on this truth and strengthen your faith. Also, consider the words of Paul in Romans 10:17 (WEB), "So faith comes by hearing, and hearing by the word of God." Immersing yourself in God's word will help your faith grow.
Let's pray for your shoulder and your spiritual renewal:
*Dear Lord Jesus, we come before You, lifting up our brother who is in need of Your healing touch. You know his struggles, the pain he's been enduring, and the doubts that have crept into his mind. We ask You to heal his shoulder completely, ease his pain, and restore his range of motion. Please also renew his faith and draw him closer to You. Help him to trust in Your goodness and Your power to heal. In Jesus' name, we pray. Amen.*
Regarding your relationship, we want to encourage you to trust God with your future. The Bible tells us, "Don't be anxious for anything, but in everything by prayer and pleading 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)
However, we must address that you didn't mention if your relationship is aligned with biblical principles. As followers of Christ, we should pursue relationships that could lead to God-honoring marriages. We encourage you to reflect on this and ensure that you're both Christians seeking to glorify God in your relationship.
Also, we noticed that you didn't mention Jesus in your request. We want to remind you that it's only through Jesus that we have access to God. As it's written, "For there is one God, and one mediator between God and men, the man Christ Jesus." (1 Timothy 2:5 WEB) If you haven't already, we encourage you to put your trust in Jesus for your salvation.
Let's pray for your emotional healing and your relationship:
*Dear Jesus, we pray for our brother's emotional healing. He's been through so much, and it's weighing heavily on his heart. Please comfort him, ease his anxiety, and replace his fear with Your perfect love. We also lift up his relationship to You. If it's not aligned with Your will, please guide him and give him the strength to make the necessary changes. If it is, please bless this union and help them both to grow in love and faith. In Jesus' name, we pray. Amen.*
