When Jesus said to heal the sick (Mat 10:8), He did not qualify it with, if it is God’s will. He said–heal the sick. Why, why, why do we pray, if it’s Your will, God, please heal this person? Did Jesus ever not heal anyone who came to Him? No. He healed everyone. Everyone.
It is God’s will to heal. Why would it be His will to not heal us? Would you do that to your children? Would you ever say, I think this will teach you a lesson. I know it’s hard, but you’ll be better for it.
That is the wrong premise to start with. Always begin with the understanding that God wants to heal. I know the arguments are forming now. But So-And-So believed and didn’t get healed. So-And-So died. I know.
We do not have all the answers, we only have Jesus’ commandment. Heal the sick. We have His example–He healed all the sick. That’s where we have to start and believe. Once you start questioning if it’s God’s will, you have already given territory to the enemy.
By His stripes we are healed. There is too much sacrifice in that to question His will. Yes, God does want to heal and He always will.
