Speaking much is not a sign of great knowledge.
A question that I am often asked is “If God cannot control man’s action, then how is He All-Powerful”? There is no doubt that God is All-Powerful. However, since He has decided to put man to the test, He has given man a freedom of choice to do what he likes. As if there was no free will, there would be no test. So, in order to test man, God has withheld His power when it comes to man and given him freedom to respond to situations in any way that he wants. Although God’s power is not visible to man today as He has withheld it purposefully, on the Day of Judgment – the day of reckoning of man – the All-Powerful God will be visible for all to see.
