Jesus said that those who have faith in him should do the same works that he did, and even greater works. If you say the same thing, then your doctrine is consistent with the gospel. This doctrine from Jesus is just as authoritative as the doctrine of the atonement or the sovereign grace of God. If you choose some things to believe from the gospel and reject other things from the gospel, then you do not in fact believe the gospel, but you believe in yourself. Those who make excuses and attempt to change what Jesus said are those who reject Jesus Christ and reject the gospel. But if you say the same thing that Jesus said, then you cannot be wrong.
Everyone must start somewhere. So start. Do what the Bible says. You can start with anything that the Bible says about the miraculous as opportunity comes, but I recommend starting with the ministry of healing. Pray for the sick. Your first concern is whether you are doing what God says, and not whether miracles are happening. You should keep doing what God says regardless of the outcome. Yes, you should indeed get results — people should receive miraculous healing. But if you do not even start, then it is useless to worry about results.
