The main physical healing of which everyone needs to have assurance is resurrection from the dead. God gives lesser healings now as a foretaste of this future healing but all by the power God has to insert life where there was previously death. He can make dead tissue live during physical healing and He can make dead bones and dust live during resurrection. He can, but that is not the only issue. The issue too is whether He will. 'If you are willing, you can make me clean' was answered 'I am willing, be clean'. He heals to show power and He heals to show willing. He raised Jesus to show power to raise the dead and to show willingness to raise the dead. We all need assurance of the willingness as well as the power of God to bring us back from the dead some day. Jesus is the resurrection and the life and He is the light we need of such things. He is therefore still healing because we still need assurance. His teachings still say 'have faith in God'. His servants still heal in His name.
