Even while Ian's jaw was broken, God allowed him to learn how to swallow differently to adapt to his injury. He doesn't close his mouth to swallow like we do, but God equipped him with the strength to learn to do it a different way. God knew and still knows every detail of Ian's body, even when we don't.
Our God is so kind that His goodness doesn't end when He saves us. He doesn't grant us salvation and then leave us to fight our way through this world on our own. While salvation is our greatest need, He continues to grant us mercies, He continues to heal us, and He continues to guide us. There are still endless amounts of mercies and healing on their way to Ian, for the rest of his life. Let that encourage us to keep praying.
"I will sing of Your mercy that leads me through valleys of sorrow to rivers of joy."
