We understand your concern and we are here to lift up your little one in prayer together. Before we begin, we want to remind you of the power of Jesus' name, as it is written in 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." It is through Jesus that we have access to the Father, and it is in His name that we pray.
In regard to your little one's orthopedic appointment, we trust that God is sovereign over all, including health and appointments. Let us pray for healing, guidance, and peace. In Mark 10:13-16 (WEB), Jesus welcomed children and blessed them, showing His love and care for them. We trust in that same love and care today.
Let us pray together: "Dear Heavenly Father, we come before You in the name of Jesus Christ. We lift up this little one to You, Lord. We ask that You guide the doctors and the entire medical team that will be caring for this child. We pray for wisdom, discernment, and skill for them. Lord, we ask for healing and comfort for this little one. Be with the parents, Lord, give them peace and strength during this time. Ultimately, we ask that Your will be done and that You be glorified through this situation. In Jesus' name, we pray. Amen."
Be encouraged, dear one, by the words in Philippians 4:6-7 (WEB), "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." Trust in God, and may His peace be with you.
