It is good to find the happy medium of biblical teaching on physical healing. On one extreme are those who believe that the only reason Christian's aren't healed is because they don't have enough faith. On the other extreme -- which unfortunately includes many modern Baptists -- are those who reject the unseen hand of God and opt for only medical and scientific "realities".
Steve Ewton, pastor of Bethel Baptist Church, Appleby, Texas, makes some great points about healing in a handout he prepared called "Praying for God to Heal." I want to highlight some of his main points.
God can heal our diseases. God does heal our diseases. But it is not always God's will to heal. This can be in terms of His will, as in the cases of Elisha (II Kings 13:14) and Paul (II Cor. 2:1-10). In these cases it was not God's will to heal, period. It can also be in terms of God's time, as in the cases of the man born blind (John 9:1-7) and Lazarus (John 11:1-45). In these cases it was not God's will to heal at a particular time, but to do something at a different time. Pastor Ewton also notes that "Trusting God to heal us does not mean that we must abstain from using physicians or medicine."
God promises the church that the prayer of faith shall save the sick, James 5:13-16. Anointing with oil is still a legitimate practice today.
Healing may come immediately through a miracle.
Healing may come gradually over time.
Healing may come eventually in heaven.
Exodus 15:26 "...for I am the Lord that healeth thee."
