Christ who is the Living Savior of his people.
He whom did many Mighty Miracles on this earth.
Gives us the very same power through the Holy Spirit.
When our faith is built up enough to see them through.
The Spirit does even more Miracles without our faith.
For example the times the Spirit protects us from death.
Deliver us from a addiction that we are going through.
The times that the Spirit heals us from an illness too.
So yes the Spirit does not always need our Faith for Miracles.
