Your prayer for your son is heard and deeply moving, and it is right to bring his physical needs before the Father in the name of Jesus.
Scripture shows us that the healing ministry of Jesus included power over sickness even at a distance. When a father came to Him at Cana on behalf of his dying son, Jesus simply spoke the word and the boy was healed many miles away. Later at the pool of Bethesda in Jerusalem, He showed that same compassion to those who had waited long for healing. These accounts remind us that His works are the works of the Father. He said that the Son does nothing on His own, but does what He sees the Father doing, and that the Father has given all authority to the Son so that all may honor Him. To believe that Jesus is the Christ, the Son of the living God, is to find life in His name.
That same Jesus made preaching, teaching and healing central to His ministry, bringing healing to every kind of sickness and disease among the people. We can trust Him for physical healing as well as spiritual healing, because He is the Son of God declared with power by His resurrection, the one whom the Father affirmed saying, this is my beloved Son in whom I am well pleased. The demons themselves recognized Him as the Son of God, and the centurion at the cross confessed the same, because His authority extends over the physical realm, the material realm and the spiritual realm.
We do not always understand why some are healed instantly and others experience a gradual healing, for there is much about healing we do not fully comprehend. But every healing process is from God. He has built healing processes into our bodies, and that natural process is no less divine because it is natural. God created nature and its processes, and whether healing comes in a moment or step by step, it is His work. We can rest in His love and trust His wisdom even when we do not have all the answers.
So we join you in prayer for your son. We ask the Father to surround him with His healing presence, to touch his body and remove every harmful side effect from his medication, to strengthen his lungs and to calm his anxiety so that his breathing is eased. We pray that God, who gives wisdom, will guide the medical team with clear discernment and skill as they care for him. And we ask that you and your son will know the nearness of Emmanuel, which means God with us, and experience the peace that comes from trusting the Son who gives life to whom He will.
May the Lord encourage your faith as you continue to look to Jesus, the Son of God, who redeems us from sin and who is able to heal and restore. We are praying with you in Jesus name.
