Lauren, I will most certainly pray for him. I do want to share something with you that i have learned over the years. Being a Christian, my faith in God is the most important thing in my life.
When we pray for a healing for someone we have to trust in God for that healing. If that person you are praying for passes from this earth, it does not mean God did not hear your prayers. He is always faithful in that aspect. His healing may come here on earth or it may come in TOTAL and COMPLETE FOREVER healing by calling him home to heaven.
I will pray for comfort, healing and above all perfect peace that surpasses all understanding.
