God is not evil. In fact God can not possibly be evil. God is all-good…infinitly benevolent. the source of everything that is good and perfect. It is important to note that evil was our idea not His. God abhors evil, it is in contrast to His very nature. However, God permits evil for several reasons.
We were created to know God and His infinite goodness and love, and to love him in response. Thsi is our purpose, what we were designed for. However, in order to love God it is necesary to have free will. Our love has to flow from the desire of our hearts, it can not be forced from us or it would not be love. And as we know, it is not enough to just say we love God. For how much could we possibly love someone if we freely and deliberatly choose to do things that we know the person detests? So it is clear that our love has to manifest itself not only by our disposition but also by our deeds. Well this is the choice we have had since the beginning. To choose God and His ways, or choose things inferior to Him and the consequences that are inextricably connected. It is important to note at this point that God loves us so much, and wants what is very best for us, namley Him. When God commands us not to steal, or lie, or be lustful, etc. He is not telling us these things because He is a control freak, but rather because He wants what is best for us. In fact He is so much in control that He lets us do whatever we want knowing He is in control. The evil in the world in not natural. It is not the way God intended it. However, God being omnipotent and so wise saw fit for evil tor eign on the earth for a time. Why would God do this? Because God works all things for good!
Now this takes into account sin, and the natural and supernatural consequenses that are inextricably connected to it. However, there are constantly things happening in this world, as you mentioned like that girl who lost her sight, that seem unjust and evil. With the incarnation, life, suffering, and crucifixion of Christ, the God-man, creation was revolutionized. Just as Christ suffered, so must we too suffer. And in different ways. The truth is we all have our crosses to carry. This is inevitable in this world. We are urged to unite our sufferings with Christ for our salvation, and the salvation of the world. In 2 Corinthians 1 we are told that the more we suffer, the more we recieve God’s comfort. Suffering is like a fire that purfies us. It purifies us, and strengthens us.
If this world were all there were, then I can see how you could cry out injustice! However, as Saint Paul the Apostle states in Romans 8:17(NLT)
“Since we are God’s children, we will share His treasures-for everything God gives to His Son, Christ is ours too. But if we are to share His glory, we must also share His suffering.
What we suffer now is nothing compared to the glory He will give us later. For all creation is waiting eagerly for that future day when God will reveal who His children really are. Against it’s will, everything on earth was subjected to God;s curse. All creation anticipates the day when it will join God’s children in glorious freedom from death and decay. For we know that all creation has been groaning as int he pains of childbirth right up too the present time.”
I like how Saint Paul uses the analogy of childbirth. It is clear that something has gone terribly wrong. And now for the present time creation is suffering, humans included. However, as a woman must suffer through the labor pains and delivery, so we too, united with Christ, under His yolk, must share in the pains, the injustices and so on of this world, but at the end of time, through Christ God will bring forth a New Creation, death and evil will be destroyed forever and ever. Christ will reign as King of Kings, and His perfect Kingdom, free of every evil, will stand for eternity.
Anyhoo, thats part of my speil. I am by no means any kind of authority. Just a fellow Brother in the Lord. I hope and pray that these words may help you to udnerstand God’s goodness and His great love for us, that they might strengthen you on your faith journey. I hope, nor do i think anything I have said in theologically unsound or in discord with what the Church teaches, however if it does, please correct me.
