Thank you for sharing your burden for your son and for inviting others to pray with you. We are joining you in prayer for him as he faces this diagnosis and the surgery that has been recommended.
Prayer is a gift that rests on relationship. Jesus gave a pattern for prayer that begins with calling God Father, and that relationship is opened to us through faith in Jesus Christ, the Son of God. Through Him we are brought into the family of God and can come to the Father with confidence. If that relationship is not yet settled, the first and most important prayer is simply asking God for mercy as a sinner and trusting Jesus alone for salvation. Once we are His children, we have this open door to bring every need to Him.
We bring physical needs to the Lord because He cares about our bodies as well as our souls. Scripture shows Jesus healing the sick and the early church continuing to pray for the sick and bringing them to the Lord. We can trust Jesus for physical healing as well as spiritual healing. He reveals Himself according to what we need, and when we need healing He is the Lord our healer who meets us in that need.
The purpose of prayer is not to make God do what we want, but to bring our hearts into line with what He wants to do. Prayer begins with God and His purposes, He stirs those purposes in our hearts, we express them back to Him, and He answers. For that reason we pray with trust in His will and His wisdom, knowing that sometimes He heals directly, sometimes He works through doctors and surgery, and always He gives grace that is sufficient and strength that is made perfect in weakness.
We take comfort that heartfelt and earnest prayer has great power when it comes from those who have been made right with God through Jesus. And Jesus said that when two or three agree together concerning a matter, He is present and hears. So we agree with you now for your son.
We ask our Father in the name of Jesus to be near your son, to grant peace to him and to you, to guide the doctors with wisdom and skill in the surgery, to bring healing and a smooth recovery without complication, and to use this time to draw him closer to the Lord. We also ask that whatever the outcome, you and your family will know the comfort of being heard and seen by God, who hears every prayer and sees every tear, and that His will and His grace will be evident in your son's life.
