I can successfully upload data using Arduino, ESP8266 and Thingspeak.
Now i need your help on how i can control my Arduino, example; blink an LED using Thingspeak Talkback.
Another example would be, Lets say i want to turn any device on or off using internet only, ie, if someone is not near the Arduino, to which all components are connected, and he/she wishes to control my devices using the thingspeak and the internet.
Any suggestions would be deeply appreciated. Thank you.

Have you looked at the section off the thingspeak documentation call "update a channel and Execute the next talkback command"?
Your program needs to read through the response it gets from Thingspeak and look for the text set by the talkback. There is some example code at http://bildr.org/2011/06/arduino-ethernet-client/ but you may have to adapt it to ESP8266
