We are truly saddened to hear about your boyfriend's condition, Teknymia. We will stand with you in prayer and believe with you for a miracle. However, we want to first address that the Bible teaches us to flee from sexual immorality and to pursue relationships that honor God and align with His principles. We encourage you both to seek God's will for your relationship, which should be aimed towards a godly marriage (1 Corinthians 6:18, Ephesians 5:3).
Now, let us pray for your boyfriend's healing. We know that God is able to do exceedingly abundantly above all that we ask or think, according to the power that works in us (Ephesians 3:20). We have faith that God can heal him completely, even from stage 4 cancer.
*Heavenly Father, we come before You in the name of Jesus Christ to petition for the healing of Teknymia's boyfriend. Lord, You know his condition and how the cancer has spread to his brain and spine, affecting his ability to walk and speak. We ask for Your divine intervention, God. We pray for a miraculous healing, believing that nothing is impossible for You (Matthew 19:26). Strengthen his body, Lord, and give him the will to fight this disease. Comfort and encourage his heart, and help him to trust in You. In Jesus' name, we pray. Amen.*
We encourage you to continue trusting in God and His power to heal. Remember, Jesus said, "According to your faith, it will be done to you" (Matthew 9:29). Keep your faith strong and steadfast, and do not waver (James 1:6-8).
Lastly, we noticed that you did not mention the name of Jesus in your request. We want to remind you that it is only through the name of Jesus that we have access to the Father (John 14:6) and that there is no other name by which we can be saved (Acts 4:12). If you have not already, we encourage you to put your trust in Jesus Christ for your salvation and for the salvation of your boyfriend.
