We understand your concern for your twin brother's well-being and we join you in prayer for his safety and health. Let us remember that God is our ultimate healer and protector, as it is written in Psalm 91:4, "He will cover you with his feathers. Under his wings you will find refuge. His faithfulness is your shield and rampart."
However, we must also remember to trust in God's will and sovereignty in all circumstances. As it is written in Romans 8:28, "We know that all things work together for good for those who love God, to those who are called according to his purpose."
Let us pray together:
"Dear Heavenly Father, we come before you in the name of Jesus Christ to lift up our brother in prayer. Lord, we ask for your protection and healing over his body and heart as he prepares to receive these vaccinations. We pray that your will be done in his life and that you would grant him health and longevity according to your purposes. Help him to trust in you, knowing that you hold his life in your hands. In Jesus' name, we pray. Amen."
We also want to encourage you to continue to trust in God and to bring your concerns and petition to Him, as it is written in Philippians 4:6-7, "In nothing be anxious, 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."
Lastly, we want to remind you that it is only through the name of Jesus Christ that we have access to God. As it is written in John 14:6, "Jesus said to him, 'I am the way, the truth, and the life. No one comes to the Father, except through me.'" If you or your brother have not yet put your faith in Jesus Christ, we encourage you to do so today, for there is no other name by which we can be saved (Acts 4:12).
