We can receive anything we need from the Lord without a gift of the Spirit operating through another individual, if we know how to believe. Dependence on the Lord directly is superior to dependence on the Lord indirectly through someone operating in one of the spiritual gifts.
What if there were no gifts of the Spirit and the Lord established that the only way we could receive from Him was through our own faith? There would be some individuals who would get born again who already had terminal diseases but didn't have enough time left to mature in their faith and receive healing. They would die if it wasn't for others interceding for them or someone with the gift of healing praying for them. That's why the Lord gave these gifts--to keep us encouraged and alive so we can mature.
It is also wrong for an individual not to mature in his personal faith in the Lord and become dependent on the gifts. It is not right for someone to receive a miracle through someone with the gift of miracles and then just struggle along until the next time that gifted minister comes through town.
The Lord wants us to receive His power through these gifts, but then we must mature so that we can walk in God's best on our own.
We are able to mature beyond a total dependency on the gifts to where we can hear and receive from God directly. But none of us will ever reach such a level of maturity in the Lord where there is nothing left to learn or receive. Receive His teachings through His Word.
