Why would Jehovah, in all His infinite wisdom allow these destructive creatures to live and exist among us? Why did God create such pests that ruin His own creation? In the sight of man, these pests are evil that destroys the crops which man has worked so hard for.
And man wonders why God allows these things to happen.
But what we need to remember is that God's plan for us is perfect and His plan is for us to prosper and succeed. Jer. 29:11
But before Adam and Eve and the creation of our world, evil already has crept through the ranks of angels in Heaven. Lucifer "chose" to blow the lights out and nurtured the darkness in his heart. He exercised his freedom to choose darkness rather than light.
So, did God create evil?
If God created all things, he must have created evil, as well, right? But like darkness, which is the absent of light, is not one someone creates. It is simply a condition brought about by the absence of light. And light, that is what God created. "Let there be light!" God never created darkness. He never created evil. And everything God created was "good". Evil is prevalent when good is absent. Evil ceases to exist when good prevails.
God created beings with freedom to choose because serving Him does not have to be an obligation, rather a choice to glorify their Maker and being grateful for the life given to them.
This "freedom of choice" is what God has created for man. A gift so that man does not become a slave or a robot in his decision making. As created beings just a little lower than the angels, we enjoy the same gift as the angels do. The idea of "freedom of choice" may be argued by many but it is only God who knows the real purpose of this gift.
