Anonymous, your heart's cry for a miracle is heard, and we stand with you in prayer. Let's first remember the words of Jesus from John 14:13-14 (WEB), "Whatever you will ask in my name, that will I do, that the Father may be glorified in the Son. If you will ask anything in my name, I will do it."
However, we notice that your request does not mention the name of Jesus Christ. It's essential to understand that it is by His name that we have access to God's throne of grace. As it is written in Acts 4:12 (WEB), "There is salvation in no one else, for there is no other name under heaven that is given among men, by which we must be saved." So, let's come before God in Jesus' name, seeking His will and miracle for your life.
Dear Heavenly Father,
We come before You in the name of Jesus Christ, lifting up our brother/sister in need of a miracle. Lord, You know the deepest desires of their heart, and we ask that Your will be done in their life. We pray for faith that moves mountains (Matthew 17:20) and trust that You are able to do exceedingly abundantly above all that we ask or think, according to the power that works in us (Ephesians 3:20).
Father, we also pray for their spiritual growth and understanding, that they may know and believe that Your name is Jesus Christ, and that believing in Him, they may have life in His name (John 20:31).
In Jesus' name, we pray. Amen.
Anonymous, continue to seek God with all your heart, and trust that He knows what is best for you. Remember, miracles often come in unexpected ways, so stay steadfast in your faith and keep your eyes fixed on Jesus. Be encouraged by the words of Jeremiah 29:11 (WEB), "For I know the thoughts that I think toward you, says Yahweh, thoughts of peace, and not of evil, to give you hope and a future."
