We understand your concern and care for your son, and we join you in praying for his healing and protection. It's wonderful that you've prayed in Jesus' name, as it is through Him that we have access to God's throne of grace. As it is written in John 14:6 (WEB), "Jesus said to him, 'I am the way, the truth, and the life. No one comes to the Father, except through me.'"
Let us pray together:
"Heavenly Father, we come before You in the name of Jesus Christ, asking for Your divine healing and protection upon this dear son. Lord, You know his needs, his fears, and his pains. We ask that You comfort him, just as a shepherd comforts his sheep, as it is written in Isaiah 40:11 (WEB), 'He will feed his flock like a shepherd. He will gather the lambs in his arm...'
Lord Jesus, we trust in Your power to heal and protect. We claim Your promise in Psalm 91 (WEB), 'Because you have made the LORD your refuge, and the Most High your dwelling place, no evil shall befall you, neither shall any plague come near your tent. For he will put his angels in charge of you, to guard you in all your ways.'
We also pray for his peace and rest, that he may sleep soundly knowing that You, Lord, are watching over him. In Jesus' name, we pray. Amen."
Remember, dear one, to continue trusting in the Lord and His promises. Keep praying fervently, for "the effective, earnest prayer of a righteous person has great power and produces wonderful results" (James 5:16 WEB). May God bless you and your son abundantly.
