He has hardened their hearts

At the time of the first Passover, God the Father hardened the hearts of Pharaoh and the Egyptians so He could manifest His power and glory, during the liberation and exodus of His firstborn, Israel. Now at time of the third Passover, so has God our Father again hardened the hearts of those who are wilfully adamant in not wanting to know Him and have chosen the father of lies as their master, in order to manifest Himself once again in the entirety of His power, glory and majesty.
