Does God still heal people?

This is a subject that keeps coming up in our Bible study. One side says: God heals whom he chooses to heal. We can get sick because we are in a world where people get sick and sometimes God will heal us miraculously other times he does not . The other side says: Yes you can get sick, but God wants to heal all and the only reason you don't get healed is because of lack of faith.
I am not sure on what side you stand, but I do know where I stand. I know that God can heal everyone. I know there are scriptures in the Bible that mention sick people without mention of them being healed. There are many scriptures in the Bible that talk about people being healed. So do all get healed? NO.
Is it because of lack of faith? Could be. Is it because God in his sovereignty chose not to heal them for what ever reason? Could be. I believe that God guarantees us spiritual healing in the Bible, I do not believe he guarantees us physical healing here on this earth.
To tell a genuine believer that is trying to serve God with all his heart that he does not have enough faith to be healed I believe is cruel. It can destroy that individual.
Should we have more faith in God and trust in his healing touch? Yes. I think we do miss out many times.
But I also know that faith is a gift from God and it is nothing we can conger up. So as the Bible says, let us ask for more faith and God will give it to us as he sees fit. Then we can stand ready to receive it, be it more faith to trust in healing or whatever God has in store.
And if we do not see a healing, lets trust God that he knows what he is doing and lets not beat ourselves up over it.

Have faith in God, don't have faith in your faith.

God bless you.
