God wishes the very best for us. The Bible tells us that His thought for us are off good and not of evil, to give us an expected end. Everything about God is good and pure. But we live in an evil world. The devil is constantly opposing every of God's plan and agenda. He doesn't want us to experience the good things that God has purposed to come our way.
This us why we need to cling on to God and the days of our lives. We can't prevent the evil from reoccurring here on earth but we can overcome them when they do come. What happens when we cling unto God is that he separates us from the evil which other people are experiencing. That was the same way he exempted the Israelites when the spirit of death was hovering over the Egyptians.
Evil is definitely going to take place but as long as we are in Christ we have no cause to fear. If our eyes were opened spiritually to see just how much God wants good for us we would be amazed. We can cause His good will over our lives to manifest when we hide ourselves from the evil intention of the devil if we choose to abide with God and do His will.
