God works in nature, in providence, in answering prayers and in determining the rise and fall of nations. It is not a rejection of God's power or presence in the world to deny contemporary miraculous claims. One must not deny that God has worked in miraculous ways at those times in history when He brought new revelation to man. Such the Scriptures affirm. When God broke into the world with revelation in the spiritual realm, He also broke into the world with miracles in the physical realm.
Miracles confirm revelation.
One must not deny the activity of God in the world today. He is still working. The nature of His work is orderly, constant and according to His laws of creation. The question is not whether or not God heals. Certainly He does.
