By studying this book, you can confirm your belief in God and love Him and all His creatures. Plantinga established that there is not any inconsistency between God and evil, in spite of John Mackie's claim.Plantinga recognizes three kinds of contradiction: Explicit contradiction, Formal contradiction and implicit contradiction. He proved that there is not any logical inconsistency between the existence of God and the existence of evil, but there is a consistency between them Mutahhary, by a different way, could receive to his three basic aims: -Dualism is wrong, and only the goods have objected to decree and ordinance of God. -The evils are essentially are not separable from the material world, then their existence have not any inconsistency with the existence of God. -He, by asserting the utilities of evils, shows that the actual material world is the best possible world and human being can even change the sufferings and difficulties and disasters to a cause of evolution, happiness and development . It seems that such combinatorial theory of Divine justice, can introduce correct logical justification of most evil state of affairs.
