Was listening to a song talking about what God planned for evil could be used for good. And this could be anything, including things that scar is. Because God uses it for us be able to reach those who are hurting. We can’t survive those always on our own, but God can.
My belief is that God created everything and everything was good. Mankind rebelled and thus revealing the nature of mankind. Rebellion is the seed to every sin. Disobedience to God brings forth the wickedness of the heart and this wickedness can easily be influenced by Satan and his demonic forces. Moral evil isnt of God. Natural events may simply just be natural. Maybe the broken arm was simply the law of gravity in affect.
But God can work to prevent evil, or bring about good when Satan attacks. God can bring good out of natural disasters. To say I dont see the good would presumed you have seen every life, every news report, spoke to every person, and examined them for years to determine if any good did come from such event. Did is strengthen them, encourage them, humble them, made the cry out for salvation.
And definitely in these moments the testimonials can help heal others around them.
