I don't believe that. Not that the Word was not confirmed, but that miracles have ceased.
To assert that they have is to assert that God's character has changed: God has been, and always be miraculous in nature. (Miracles being defined as God's direct interaction with the universe, esp in a physical way.)
There are many passages where God is directly portrayed as a lover and Israel/the-Church as his beloved; now factor in the distinctly male urge to impress his girl and rereading some of those passages and it seems obvious to me that God's saying "now watch this!"
In short, God still works in the Earth and in the lives of men, directly and indirectly.
I emphatically agree but I believe that God does not require visible miracles to work his will.
