After adding the Frame-relay Map statement, as suggested by several people, I was able to ping the local serial Interface. I then created the interface as a Sub-interface and attempted to use the Frame-relay map command and received the "You should use the Frame-Relay Interface-dlci" command from the router. When the Tnterface-dlci command was applied to the sub-interface (s0/0.1) IP traffic began passing back and forth on the serial link. I also had to add the appropriate static route to the default gateway, as suggested, so other clients on the development network (192.168.1.0) would know where to send traffic destined for the test network (192.168.3.0) or the Intermediate network (192.168.4.0). Routes had already been setup on the routers, but the default gateway did not know about the 192.168.4.0 network until I added the static route. After adding the route all traffic successfully was passed from all clients to the Test network via the intermediate successfully. I understand now why I had to assign the Map statement to the global interface, so that layer Layer 3 knows which layer 2 interface to use, what I am still a little confused about is why the command changes when applied to a sub-interface to Frame-relay interface-dlci instead of Frame Relay Map IP. I appreciate all responses they all helped me to troubleshoot and understand the Frame Relay technology successfully, thank you.
