The question says, “If God is real and he has the power, why has he allowed so many school shootings?”
Found this in my bible.
Remember, God is always there. We live in a world where Satan is in control of everything, but when Jesus comes back everything will change. Those that commit horrible acts will meet with him face to face if they don’t repent. But do not blame God for these horrendous acts, that is the devil, God doesn’t like when events like this happen. He is always there.
