We join with you, Windwold, in praying for your son's healing and strengthening. It is so important that you have come to us asking in the name of Jesus. God hears us when we pray in His Son's name. Jesus said in John 14:13-14 WEB,
If you will ask anything in my name, I will do it. If you love me, keep my commandments.
First lets rebuke this sickness. We take authority over this COPD and asthma, and we command it to leave your son's body. We speak healing and restoration to his lungs and respiratory system. We pray for his immune system to be fortified by the power of the Holy Spirit, enabling him to overcome all illnesses.
Father, we ask You to heal his cough and restore his ability to breathe easily. We thank You for Your healing power and for Your unfailing love and faithfulness. We trust in Your promise in Psalm 103:2-3 WEB,
Bless Yahweh, my soul, Don’t forget all his benefits, who forgives all your sins, who heals all your diseases.
As we pray and believe for your son's healing, we also encourage you both to draw near to God, trusting in His goodness and grace. Remember that God's will is for your son to be in good health and to prosper in all things, just as his soul prospers (3 John 1:2 WEB).
Continue to stand firm in faith, knowing that God is able to do immeasurably more than all we ask or imagine (Ephesians 3:20 WEB). We will pray with you continually until we hear a good report of your son's complete healing.
