I have a Westinghouse furnace in my home. I woke up to a cold house this morning. The pilot light is the only thing that is on. There is electricity. The only thing i noticed was that the round Honeywell thermostat does not give a little spark when i change it from cold to hot.

Hello jobo. Welcome to the Heating and Cooling Appliance forum and the Do-It-Yourself Web Site.
That tiny blue spark is caused by the low voltage electricity which is coming from the transformer. Be sure there is electrical power to the heating unit first.
If power is at the heater, test for power at the transformer. There should be about 24-32 volts of DC current.
If power is there, remove the entire thermostat from the wall and test the thermostats Red and White wires.
If none is present, could be the wiring is broken, not connected or the thermostat is defective.
If you suspect it's a defective thermostat, connect the two wires {Red & White} together and the heater should operate and function.
